Everything Old Is New Again: Goodbye To The VCR

This past summer, the Funai Corporation of Japan decided to stop manufacturing videocassette recorders (VCRs) after several decades, citing their inability to source parts as the reason.
What’s that you say? You didn’t even know anyone was STILL making VCRs in 2016?
A reporter for the Washington Post was referred to me by The Society of Motion Picture and Television Engineers (SMPTE) for some pithy quotes about the demise of the VCR, which had its debut in the United States 40 years ago this past summer. Yes, the ½” videocassette format has been around for some time, with the most popular iteration being the VHS format developed by Japan Victor Corporation, better known as JVC.
Sony also had a ½” videocassette format for home use called Betamax, and in many ways, it was a better way to record and watch TVs shows along with movies. But Sony’s insistence at keeping Betamax a proprietary format (a la Apple with Mac OS and iOS) eventually doomed it.
In contrast, JVC licensed VHS to a long list of companies: Panasonic. Hitachi, Philips. RCA. Zenith. GE. Sharp. You name the CE company; they probably sold a VHS VCR at some point. And that had a lot to do with the success of the format, which soon migrated to consumer camcorders. There was even a short-lived digital version (D-VHS) for recording HD programs and playing back movies in HD, starting in the late 1990s. Blu-ray soon killed that off, though.
When you think about it, the VCR was really at the top (or bottom) of a family tree that leads directly to today’s streaming, on-demand video services. And here’s why – the VCR created the concept of time-shifting; recording a TV program so you could watch when you wanted to, not when CBS, ABC, or NBC said you could.
VCRs also gave us the ability to skip through commercials, pause, and rewind to watch a clip over and over again. Or the entire show, for that matter. After Hollywood lost the famous Sony vs. Universal Studios Supreme Court decision in early 1984 – which ruled that making recordings of TV shows for home viewing was considered “fair use” under copyright statutes – the floodgates opened.
Not long after, studios started making movies available on VHS and Betamax cassettes for sale. Enterprising individuals, noting the $90 and $100 price tags for movies on cassette, opened small video rental clubs. For having your credit card on file, you could rent a movie for $5 or $6, making sure to rewind it (or paying an extra fee) and returning it for another movie.
Hollywood studios weren’t happy with this turn of events until smarter heads realized the additional revenue stream could add millions to the bottom line. And so companies like Blockbuster and Hollywood Video came into existence, happily raking in the cash as stacks of rental cassettes walked out the door every night.
The introduction of the DVD format almost 20 years ago (yes, it HAS been that long!) posed an immediate threat to the VHS format. (Betamax had long since folded its tent and left town.) Now, you didn’t need to rewind anything, and there was no annoying, blinking “12:00” indicator staring at you the entire time.
Bet of all, you could now jump through chapters of a movie by looking at I-frames. Fast forward, pause, and reverse were still available, but in theory, an optical disc would long outlast a VHS tape. It didn’t take long before video rental stores started replacing VHS tapes with DVDs, and by 2005, it was almost impossible to find a movie on VHS.
That was the first year that DVD sales began to decline, although rentals held their own for a few more years. Looming on the horizon were two new HD optical disc formats – HD DVD and Blu-ray – and Hollywood was giddy anticipating wheelbarrows of cash coming in. (True fact: The first Austin Powers movie was largely ignored at the box office and made most of its money through DVD rentals and purchases.)
But there was a fly in the ointment. About 7 years earlier, a company called TiVo unveiled something called the digital video recorder, or DVR. This gadget would let you record analog broadcast and cable TV programs to a hard drive – no tape or disc needed. TiVo sold a subscription program guide service, which is where they made most of their money. I had one of the first Philips-made TiVo units (14-hour capacity) and bought a lifetime subscription for $99 back in 1999, using a dial-up connection to refresh the program guide.
So now we could record a TV program, skip the commercials; fast-forward, pause and rewind, and simply delete the file when we were done. “Did you TiVo Letterman last night?” soon became water cooler talk. Along the way, we had obviated the need for any kind of recording media – tape or disc – in favor of solid-state storage.
A year after DVD sales started their decline, I bought one of TiVo’s first HD DVRs. It accepted CableCARDs, so it would work with Comcast. And it had dual DVRs (Wow!) so I could record two programs at once. It was big and noisy, but it served me well for 9 years.
Along the way, companies like Comcast, Time Warner, Charter, Dish Network, Verizon, and DirecTV came out with their own DVRs, some of which could record 4 or more shows at once. Now, you could record movies in high definition and watch them at your pleasure on your brand-new big-screen plasma or LCD TV.
And that brings us to the present day. Hollywood Video is long gone, and Blockbuster is bankrupt; its assets bought by Dish Network. The Blu-ray format, having vanquished HD DVD, isn’t the cash cow that Hollywood anticipated as more and more video and movies are watched via ever-faster streaming connections. DVD players – once selling for $1,000 – can be found for $19.99. And Blu-ray players with WiFi are widely available for about $50 – $70.
Netflix has now evolved into a streaming media monster, as has Amazon. YouTube, a pioneer in streaming shared videos, now offers a “red” premium tier, free of commercials. HBO and Showtime, along with ABC and CBS, have started subscription streaming services that can be purchased without a cable or satellite subscription. Episodic TV series are being produced for streaming channels and they’re not scrimping on production values.
So we’ve come full circle. My Comcast Xfinity set-top box is a DVR, but it streams channels from a cloud server, not from an internal hard drive. My contacts at Comcast tell me we’re not far from the day when there won’t be any set-top (or sidecar) receivers at all – your smart Ultra HDTV with WiFi will do all the heavy lifting. (After all, smart TVs are basically computers with big display screens these days.)
Today, you can go quite happily through life without having to wind a tape or load a disc in order to watch HDTV. And that’s exactly the way things were forty years ago. Weird, right? Except you now have hundreds of channels to choose from; all of which can be streamed on-demand depending on the service you subscribe to.
Time-shifting. Commercial skipping. DVDs. Blu-ray. DVRs. Chapter searches. Video streaming. All of these grew directly out of that first VHS VCR that was sold 40 years ago.
And all you need to watch it is a smart TV and a remote. Everything old is indeed new again…
USEFUL GADGETS: Three Antennas and a Preamplifier for Cord-Cutters

The cord-cutting landscape has changed considerably in the past twelve months, and it’s no longer a fad, but a growing trend as more and more consumers decide that they can get by just fine without expensive pay TV channel packages.
In fact, Comcast reported yesterday that they now have more subscribers for broadband service than for pay TV channels, which accords greater importance to Comcast’s failure to acquire Time Warner: The combined companies would have controlled broadband distribution to a disproportionate number of U.S. homes.
While Internet service is the key part of cord-cutting, free over-the-air television still pays an important part. Think of the Super Bowl, the NHL Stanley Cup and NBA championships, and the NCAA Final Four championship game.
But there’s also a lot of good programming on free TV right now. In recent months, my wife and I have used our Channel Master DVR+ and TiVo HD to time-shift and watch The Blacklist, American Crime, Brooklyn 9-9, The Good Wife, 60 Minutes, American Odyssey, CSI, Blackish, Saturday Night Live, and Mr. Selfridge (plus a host of one-time PBS programs).
Throw in some Netflix streaming (House of Cards) and there’s plenty to watch without Big Cable. So a balanced cord-cutting approach should incorporate both broadband and terrestrial broadcast TV.
To get the former, you need a fast Internet connection and a late-model Wi-Fi router. To get the latter, you only need some sort of antenna to connect to your television or receiver/DVR, like the Channel Master box, TiVo’s Roamio, Tablo, or Mohu’s new Channels product.
Blessed with a few days of nice weather, I decided to excavate my pile of review products and found three antennas patiently waiting for testing. The first was a rather odd-looking design from HD Frequency, called the CC Aerowave ($49 with 12’ cable from www.hdfrequency.com). It resembles a small window with a 75-ohm coaxial balun attached to the inner corners of two panes.
The second antenna came all the way from Australia and goes by the name HD Quad ($39.99 from www.hd-quad.com). It’s a flexible, transparent antenna with UHF collinear elements, not unlike many other antennas I’ve tested.
The last antenna is a bit larger and is a six-element VHF/UHF yagi, and comes from Channel Master. The StealthTenna 50 (CM3010HD, $29.00 from www.channelmaster.com) can be mounted indoors or outdoors. It’s small enough to sit in a closet or attic space, or even in a room – think of it as functional art.
I also found a new inline signal preamplifier from Antennas Direct. The Juice UHF/VHF Amplifier ($79.99 from www.antennasdirect.com) can be used inside or outside and provides about 18 dB of signal boost with a low noise figure, which is real handy in areas where TV reception can be problematic. (Successful digital TV reception is all about signal-to-noise ratio!)
For this round of testing, I dusted off my tried-and-true UHF bowtie antenna, once available from Radio Shack but largely ignored by retailers today. (Seriously – how many of them want to sell a $5 TV product?)
I set the bowtie up on a folding table in my home office and attached it to a large cardboard box with masking tape. While that part of the test was decidedly low-tech, I then connected the antenna lead into a two-way splitter, with one leg going to a spectrum analyzer and the other going to a Hauppauge Aero-M USB tuner, connected to my Toshiba laptop.
This arrangement allowed me to see the actual waveform and signal strength of each TV station under test. I could then verify successful reception with the Aero-M, and to close the deal, look at the actual MPEG-2 video stream from each station using TS Reader. These three measurements gave me a very concise report on the performance of each antenna.
If you go back to my last round of testing in November of 2014, you’ll see that I used the same antenna position (different box, though!) and same test gear. The only possible differences in testing would come from the amount of foliage on nearby trees, as my house is partially blocked from the Philadelphia/Roxborough antenna towers over a20+ mile path. (In other words, an ideal site for indoor TV antenna testing!)
The Philadelphia TV market is unique in that it has two high-power, low-band VHF TV stations – KJWP (IND) on channel 2, and WPVI (ABC) on channel 6. There are only 40 or so low-band DTVs in operation nowadays as that part of the RF spectrum is susceptible to impulse noise and strange propagation enhancement. Antennas that work well from channels 2 through 6 (about 54 to 88 MHz) are also very large – a half-wavelength dipole for channel 6 needs to be about 68 inches long!
There’s also one high-band VHF operation on channel 12, WHYY (PBS). The rest of the Philly DTV stations are active on the UHF band, starting at channel 17 (WPHL) and ending at channel 42 (WTXF (FOX)). In addition, I can easily pick up three DTV stations from the Allentown area: WBPH-9, WLVT-39 (PBS), and WFMZ-46 (IND). There’s even a repeater for WTXF on channel 38 that shows up on my home antenna array, plus WNJT-43 in Trenton.
I picked a handful of stations to verify reception: WPVI-6, WBPH-9, WHYY-12, WPHL-17, KYW-26 (CBS), WUVP-29 (UNI), WCAU-34 (NBC), WYBE-35 (IND), WLVT-39, WTXF-42, and WFMZ-46. Any of these antennas would be doing an outstanding job if they grabbed all of these stations, as their signal levels vary widely and there’s about 113 degrees directional offset between the Roxborough and Allentown antenna towers.
The first measurements were made with the bowtie, but unamplified and with the Juice amplifier connected. I then repeated these measurements with the HD Quad, CC Aerowave, and StealthTenna 50; again, unamplified and amplified. (I’ll have separate comments at the end of this article on the performance of the Juice amplifier.)
Perhaps the toughest signal to pull in is WPVI on channel 6. Two of the review antennas aren’t really designed for low-band VHF reception, but WPVI runs quite a bit of power and manages to get picked up by brute force on many antennas. (None of the test antennas could pull in KJWP-2 reliably). The rest of the stations aren’t quite as challenging to pull in.
Table 1 shows the results of my tests. Amplifiers do make a big difference, and helped the lowly bowtie antenna and StealthTenna 50 capture first place with 9 out of 11 stations received reliably (i.e. no drop-outs for at least a full minute). To be fair, the StealthTenna 50 is a much larger, directional antenna than the CC Aerowave and HD Quad, both of which should behave like dipoles with classic figure-8 patterns.
Table 2 ranks the antennas by performance. The bowtie by itself wound up in a three-way tie for second place with the amplified HD Quad and bare-bones StealthTenna 50, grabbing 8 out of 11 signals. Following behind was the amplified CC Aerowave, having received 7 out of 11 stations successfully and the bare-bones HD Quad with 6 out of 11 stations.
The Aerowave was a puzzler. By itself, it only received one station – WFMZ on channel 46. I experimented with laying it flat and orienting it at right-angles to the Roxborough antenna farm to try and improve reception, and oddly enough, both of these alignments were more successful than simply positioning the antenna with its face in the correct compass heading. Lying flat, it picked up 4 of 11 stations successfully, while angled at 90 degrees, it grabbed 6 of 11.
The literature supplied with the Aerowave says you can “position the antenna in any desired location,” but based on my results, you may be futzing with it for a while to get the best reception – something I didn’t have any problems with when using the Mohu Leaf, Ultimate, and Winegard FlatWave antennas last November.
ADDING SOME JUICE
Antenna Direct’s Juice amplifier worked much better than expected. Its specifications call for 17.5 dB of gain on VHF channels and 19 dB of gain on UHF channels. (10 dB = 10 times the signal strength, with each 3 dB in gain doubling the previous signal level.) The amplifier’s noise figure was specified as below 2 dB in the VHF bands and below 3 dB in the UHF bands.
In my tests, the Juice boosted WPVI’s signal on channel 6 by about 15 dB and raised the noise floor from about -87 dBm to -85 dBm – or 2 dB, as the specifications claim. All amplifiers generate noise, and a good design will keep that to a minimum to avoid spurious signals and interference to desired signals. (Cheap amplifiers won’t!) Performance was comparable on channels 9, 12, and even 17, where I saw signal levels increase by about 18 dB.
At the high end of the UHF band, I saw an improvement of 20 dB with an increase in noise figure of about 2.5 dB, using WFMZ’s powerful signal on channel 46 for testing. That’s excellent performance for a UHF amplifier and rivals that of the Channel Master Titan-series mast-mounted amplifiers I’ve been using for years. (Titan 2 VHF/UHF 16 dB $65.00, Titan 2 VHF/UHF 30 dB $69, both available from www.channelmaster.com)
I don’t have any data on the Juice’s resistance to intermodulation signal distortion (or overloading from very strong in-band and adjacent-band signals), other than to say that the dozens of very strong FM radio carriers that also broadcast from Roxborough didn’t create any reception issues for me with channel 6 when the amplifier was inline.
It is amazing how little antenna you need to achieve indoor TV reception. My location is sub-optimal in this regard, given my distance to Roxborough and the number of obstructions in my path.
Yet, with just a $5 bowtie antenna, I was able to receive eight TV stations reliably (5 from Philadelphia and 3 from Allentown), including all major networks (CBS, NBC, ABC, Fox, and PBS). Adding the Juice amplifier brought in one more station, and probably fiddling with the bowtie position would have captured the remaining two on my list.
Channel Master’s StealthTenna 50 isn’t exactly small, but you can put it in tight locations indoors for reception, such as a townhouse attic. You can even install it on top of a shelf, or in a closet, and with an amplifier, it will do an excellent job – just use one of the many TV reception Web sites (TVFool.com is the best) to determine the compass heading and where to aim your antenna.
The HD Quad behaves like many other collinear antenna designs I’ve tested. It’s transparent, so you can hang it in a window, and it is a better performer on UHF channels than on VHF. Add an amplifier to it and you may grab a few more channels. One bonus – you can roll it up and take it with you on trips, as I often do. Hook it up to a USB tuner stick and you can watch local HDTV on your computer in hotel rooms.
The CC Aerowave was, to put it mildly, a disappointment. I even tried moving it to different locations, using the spectrum analyzer to peak the signal and see if I could improve those reception numbers. No dice! Some signals that wouldn’t come in at all were now just intermittent with frequent dropouts and frozen images. Adding the Juice amplifier didn’t help much, so I can’t recommend this antenna.
Finally, Antennas Direct’s Juice amplifier is a solid performer and delivers the goods. A noise figure approaching 2 dB in the UHF TV band is excellent performance for the price. There is a puzzler, though – although this amplifier is obviously weatherized, it doesn’t come with a mounting bracket for installation on a mast, which is the best place to out it to overcome signal loss and noise in the antenna downlead. Something for the AD folks to figure out…
Antennas, Antennas, On The Wall…Who Has The Best Reception Of Them All?

It’s been a L-O-N-G time since I conducted tests of indoor TV antennas. More than a year and a half, to be exact. Yet during that time, various samples have been showing up at my door to be added to the “eventually get around to it” pile in my lab.
Well, I eventually DID get around to it. Some downtime this week gave me the motivation to haul out all of those production samples, set up my spectrum analyzer, and also give Channel Master’s new DVR+ ATSC receiver/DVR a workout.
Unlike my past tests, which took place mostly in northern New Jersey, I opted to stay at home this time and give each of the contenders a shakeout in my upstairs office. Indoor DTV reception at my house is by no means easy – my location is over 20 miles from the Philadelphia (Roxborough) TV towers, and according to TVFool.com, I have a 2-Edge path, meaning there are some hills in the way.
Still, there’s enough RF coming into the room to make this test worthwhile. And my timing couldn’t be better, as numerous research reports and news stories show that, slowly but surely, an increasing number of homes are “cutting the cord” and using a combination of free, over-the-air TV with Internet streaming to get their daily fix of video.
A recent report by The Diffusion Group shows that 14% of all broadband homes don’t subscribe to pay TV, up from 9% in 2011. The report states that about 75% of U.S. households now have broadband service, so that means 13 million homes are doing just fine without the likes of DirecTV and Comcast.
Significantly, 2013 was the first year that pay TV companies saw a net loss of subscribers, even though it was only several tens of thousands. But that result flew in the face of experienced analysts who predicted only a few years earlier that consumers would never give up on cable and satellite television subscriptions.
Funny thing about that: At some point, the monthly cost of pay TV channel packages got so high that people reached their breaking point and said, “Enough!” It’s no surprise that Netflix has more subscribers than Comcast, Time-Warner, or any other MSO (50 million and growing in the U.S.). And it’s even less of a surprise that HBO and CBS announced video streaming services last month to reach cord-cutters: They’ve clearly read the writing on the wall.
While those stories are compelling, they’re beyond the scope of this review. So let’s refocus on the task at hand, which is to determine how well each of the test antennas performed with the DVR+.
Mohu, who has developed some pretty clever antenna designs, sent along their Leaf Metro ($24.99) several months ago. This compact package bears a remarkable resemblance to the trusty UHF bow-tie antenna that decorated so many old tube TVs back in the day, and which was eventually dropped from most product lines because (a) it was too inexpensive, and (b) it didn’t look cool enough.
Mohu’s Leaf Ultimate ($69.99, now called the Leaf 50) has also been sitting on the shelf for a while, and I did hook it up for one of my previous antenna tests. Unlike the Metro, the Leaf 50 is an amplified design and uses an external preamp cartridge that installs in-line and uses either USB power from your TV or a supplied wall transformer.
Rounding out the Mohu triumvirate is the Curve 30 ($49.99), another rectangular-shaped flat antenna that sits on a shelf with a supporting bracket. It doesn’t use an amplifier and is intended for close-in (30 miles or less) operation.
From Antennas Direct, we have the ClearStream Eclipse ($59.99) with inline amplifier. It’s not much more than a tapered loop, but what’s unique about this design is the adhesive attached to the front of the loop: Simply peel off the protective backing and stick it on a window. Or wall. (Or an annoying relative who’s fallen asleep on the couch.)
From Winegard, we have the FlatWave Amped ($64.99), a flexible multi-band antenna with preamplifier embedded in the housing, right where the mini coax attaches. Like the Leaf 50, the FlatWave Amped can be attached to just about any non-metallic surface or just hung on a wall.
Finally, just for fun, I threw in an RCA ANT1050 ($12.99) that I had replaced with a Mohu Leaf earlier this year for a friend’s sports collectibles store. This is a strange-looking design, but is basically a pair of folded dipoles in a flexible plastic housing that you can attach to just about any surface.
And for even more fun, I dug up one of my trusty UHF bowtie antennas to use as a “control” for all of my tests. When Radio Shack used to sell these, they cost all of $3.99 a pop. And therein lies the problem – there’s just no money to be made selling these anymore; not when you can get ten times that amount of money for a flexible antenna design.
For this test, I went with a simple but reliable methodology: I set up the bow tie antenna on a small table, in a spot where my spectrum analyzer indicated good signal levels on VHF and UHF. The feed from the bow tie went to a two-way splitter, and two identical 10’ lengths of RG-6 connected from there to the DVR+ and to my analyzer.
After running a channel scan on the CM DVR+, I “looked” at each received channel with the analyzer (and captured numerous screens as JPEGs for reference). Then, I switched the antenna feed over from the analyzer to my Hauppauge Aero-M receiver (plugged into my laptop) and used TS Reader to look at the MPEG stream from each station that was successfully received. If I saw nothing but green bars and a low bit error rate (BER), the station was logged under the “Yes” column. If I saw tiling or signal break-up, it was logged as “Int” for intermittent. And if the station didn’t come in at all, or only briefly, it was pushed to the “No” column.
After testing the bow tie, I repeated this procedure for each review antenna. The Curve antenna used its own support in the same test location, but all other antennas were attached with masking tape to a cardboard box to hold them in place in the “sweet spot.” Not elegant, but effective. (I didn’t remove the adhesive from the ClearStream Eclipse.)
This was about as fair as I could make the test. No antenna was positioned in a more favorable location than any other antenna – I just picked a spot, attached or stood up each antenna, connected it, and tried to watch TV stations, just like the average person would at home. Except they wouldn’t have had the advantage of an analyzer to find the best place to set up.
After logging plenty of transport streams, switching through channels, and grabbing analyzer screens, I came up with the results shown in Table 1. Depending on where you live in the metro Philadelphia area, there are 16 to 18 separate digital TV stations that can be received indoors. Three of them are in the Allentown/Bethlehem area, and one (WNJT) is in Trenton, NJ.
Amazingly, I found 11 stations that were consistently strong with most models – not all – and decided to use those for my test: WPVI-6 (in the no-man’s land of low-band VHF), WBPH-9 and WHYY-12, WPHL-17, KYW-26, WUVP-29, WCAU-34, WYBE-35, WLVT-39, WTXF-42, and WFMZ-46. WBPH-9, WLVT-39, and WFMZ-46 are all up in Allentown, and the rest of the signals come off the Roxborough towers. (Note that the channel numbers given are for each station’s physical (RF) channel, NOT their virtual channel. For example, KYW uses channel 3, while WTXF uses channel 29 and WFMZ uses channel 69. )
A few other stations popped up briefly during scans, but none of the antennas could pull any of these in consistently. I left them out of the test. Even the DVR+ was able to read and capture some elementary PSIP information for these stations, like their virtual channel table (VCT) and call sign. But capturing basic PSIP information doesn’t mean reception was successful.
The most surprising thing I learned from this round of tests was that the cheapest antenna – the bow tie – was also the most reliable. This design was really intended for reception of UHF stations and was intended to clip on to an extended rabbit ear. Yet, it pulled in ten of the eleven test stations without a hitch, having trouble only with WPVI on channel 6. That’s not a surprise at all, given how inefficient a bow tie would be at 86 MHz! (And it was only $3.99!)
There was a two-way tie for 2nd place between the Leaf 50 and FlatWave Amped. Again, not a surprise – both of these antennas have fundamentally good designs based on collinear elements, and their built-in preamplifiers raised signal levels sufficiently to provide a strong signal-to-noise (SNR) ratio. That’s critical for DTV reception, especially with multipath! The Achilles Heel for both antennas was VHF reception; specifically, WPVI-6 and WBPH-9. Channel 12 locked up beautifully as did all of the UHF stations.
The Leaf Metro, which physically resembles a bow tie, came in third with eight stations received successfully and three intermittently. Oddly, those three stations were WBPH-9, WUVP-29, and WTXF-42; it wasn’t an either/or VHF/UHF thing. Maybe some more futzing around with antenna placement would have cleaned things up. But you can’t complain for $30 with this model.
The ClearStream Eclipse and the RCA ANT1050 were both disappointments. Each antenna only pulled in seven solid signals, all in the UHF band. Channel 6 was a no-show on the ANT1050 and troublesome on the Eclipse, and vice-versa for channel 9. The Eclipse, even with an amplifier, couldn’t handle channel 12, but the ANT1050 was happy with it. However, the ANT1050 couldn’t lock up WCAU’s NBC signal on channel 34 (ironic, considering what was once RCA used to own what was once NBC!).
The Mohu Curve, bringing up the rear, was to be truthful kind of a flop. It only snagged five stations successfully – two on VHF and three on UHF – while passing on some easy, strong channels like WPHL-17 and WCAU-34. It also had trouble with WPVI’s broadcast on channel 6.
Again, it might take some futzing around to improve reception with this model, which is probably better used within a 10-to-15-mile-radius around the TV towers and not 15+ miles away. This isn’t the first time I’ve tested a decorative or camouflaged antenna – RCA had a curved picture frame model about ten years ago – and they usually come up short for some odd reason.
OK, everyone can stop nagging me now. I tested every antenna I could find, save for an Australian model that must have come in some time ago and had a PAL-type RF connector for which I had no appropriate adapter. Most of these antennas deliver the goods: I’ve always been a big fan of the basic Mohu Leaf design, despite its lack of gain at VHF frequencies. It’s unobtrusive and works very well.
Winegard’s FlatWave, the answer to the Leaf, also pulls its weight. Both it and the Leaf scored highly in my last test of indoor antennas in March of 2013. (Wow, was it REALLY that long ago?) And things only got better with the amplified versions of each model. I didn’t see a significant degradation of the noise floor here when they were switched on (< 2 dB) and they made a difference on the weaker signals. Use either of these if you are 15 – 30 miles out from the TV transmitters and have a reasonably clear reception path, i.e. maybe a small hill or some buildings in the way.
The Metro has everything – good performance in a small, inexpensive package. I’d recommend this one for city dwellers, and you shouldn’t need any additional amplification. Closer to the transmitter, it should pick up low-band VHF stations nicely, but since there are only about 45 of them in the entire country, that’s not a big issue for the average user.
I can’t recommend any of the last three models, given how many strong stations they couldn’t pull in. The Curve is best used by city dwellers or close-in suburbs, but only if you want to make a fashion statement. Otherwise, go with the Metro and stick it on the wall or in a window. The ANT1050 is certainly cheap, but missed too many easy stations. And the Eclipse is clearly challenged with low-band and high-band VHF reception.
Still, isn’t it amazing how well the bow tie antenna worked? If you can’t find one at a flea market or surplus store, you can make your own easily enough – there are several Web sites that show you how to do it. And your cash outlay will be minimal. Gosh, $3.99 won’t even buy you a tall coffee at Starbucks these days…
CONCLUSIONS: CHANNEL MASTER DVR+
This product isn’t getting as much attention as it should. The super-flat DVR+ (not much thicker than a Leaf or FlatWave) has a full ATSC receiver and dual DVRs. It uses the program guide transmitted by each digital TV station to show you what’s on and to set up recordings.
Two accessory USB ports are provided for a Wi-Fi adapter and external storage (internal storage of 16 GB amounts to only about 2 hours of recording). There’s also an RJ-45 port for wired Ethernet connections, helpful when your box does a software update. The connection to your TV is through HDMI with embedded audio, and a separate optical port is provided for AV receivers.
The DVR+ isn’t nearly as fast at scanning for channels as the LG 47” TV I have in the same room, but it eventually finds them all. The receiver locks up quickly on clean VSB signals, making it a perfect receiver for my antenna tests. CM has also included direct connections to Vudu and Pandora through their program guide (powered by Rovi!), although Netflix probably would have been a wise addition considering their streaming video market dominance.
I’ve used the DVR+ to record blocks of CBS programs whose schedules are thrown out of whack by late-starting Sunday NFL games that end somewhere in the vicinity of 8 PM EST, and its multi-speed fast-forward/reverse search works quite well, even if it doesn’t have the tactile feedback of a TiVo DVR. Of course, the DVR+ is a LOT cheaper at $250 and there’s no monthly fee for program guide information, as it comes automatically from each TV station.
Given the paucity of conventional set-top boxes for off-air reception, this is one of your better choices and sure beats watching HDTV on your phone, tablet, or computer. Let’s face it; Tom Brady’s Patriots vs. Payton Manning’s Broncos is a lot more compelling on a big screen TV than an iPad!
See you next time I get a pile of antennas…
Editor’s note: Channel Master also offers a 1 TB version of the DVR+ for $399.
Aereo And The Law Of Unintended Consequences

For readers who aren’t up to speed, Aereo is a new service that receives terrestrial digital TV broadcasts in major markets and re-transmits them over the Internet, using AVC coding with IP headers. The concept is to provide local reception for those who can’t pick up these signals for one reason or another on their regular TV.
Now, the devil in the details: Ever since Aereo launched a couple of years ago, it has been in court, fighting off challenges by the major broadcast networks who are crying “foul!” and saying that Aereo’s retransmission is a violation of copyright laws. They also claim that Aereo owes them retransmission fees.
Aereo’s rebuttal and defense centers around a flimsy (to me) technical argument: Each subscriber gains access to an individual antenna about the size of a dime, which then is connected to an individual receiver, decoder, DVR, and encoder. It’s as if the subscriber built his or her own TV antenna system, which is certainly within their rights.
I remain skeptical because the cost of actually setting up thousands of individual antennas, terrestrial receivers, video decoders, and video encoders would be prohibitively expensive and never be recovered by the $8 monthly subscriber fee (for 20 hours of recording time, $12 for 40 hours).
And anyone who has ever taken a modicum of courses in electrical physics and RF theory knows that (a) the tiny antennas Aereo assigns to each subscriber can’t possibly have enough gain to work for high band VHF reception, let along UHF reception, and (b) the close spacing of those antennas – as seen from earlier PR photos released by the service – means they interact with each other to form a larger array, based on the principles of inductive and capacitive coupling. That, in essence, is a master antenna TV system – delivering TV channels to many viewers, not one.
Thanks to a sub-par presentation by expert witnesses called by broadcasters at the first hearing, the 2nd Circuit Court (New York City) ruled 2-1 that Aereo didn’t infringe on copyrights and cited the earlier Cablevision “cloud” DVR decision as precedent. Aereo’s right to operate was subsequently upheld in the 1st Circuit (Boston). Service is active in both cities now.
However; two weeks ago, Aereo was rebuffed by a 10th Circuit judge in Salt Lake City, who unequivocally stated that “The plain language of the 1976 Copyright Act supports the plaintiffs’ position. Aereo’s retransmission of plaintiffs’ copyrighted programs is indistinguishable from a cable company.” As a result, Aereo had to shut down its service in Salt Lake City and Denver for the time being.
While this case winds its way on to the Supreme Court, another twist in the story has surfaced. Apparently subscribers in New York City had massive problems with the Aereo stream of the Oscars telecast on WABC-TV a week ago Sunday. Consequently, the company’s Twitter feed was lit up with complaints about “buffering” and “locked-up pictures.”
Here are some of the dozens of tweets I found: “Awful service, bad image quality & not recording scheduled shows but it sad you treat ORIGINAL customers the way you do.” “It goes out now and then requiring me to select Oscars all over again. Common? I have it on auto quality.” “Thanks for doing work on the site tonight. It’s not like I wanted to watch the Oscars. No big deal.” (Gotta LOVE that sarcasm!)
And more: “C’mon Aereo. Get your s–t together.” “Anyone else watching the Oscars using Aereo like me? S–t keeps buffering every 30 seconds. Frustrating the hell out of me.” “Hmm is Aereo down for anyone else? Is it just an East Village or Roku thing? #CordCutting fail during the Oscars” “@Aereo Support I keep getting the message “The Oscars has ended.” A total of 8 seconds recorded. Worst. Oscars. Ever.”
This one was my personal favorite: “@Aereo I don’t have time to run to Best Buy and buy some rabbit ears right now.” Well, maybe that would have been the best thing to do.
A couple of observations are in order. First, I don’t know how exactly Aereo has its front end configured, but if they’ve actually tried to keep every single subscriber’s hardware separate by various technical tricks to pass legal review, then they might have run out of server capacity and brought this service failure on themselves. (Apparently this also happened during the Golden Globes, according to a story on the Quartz Web site.)
There is a reason why cable and satellite companies use a single receiver for each broadcast and premium channel they carry, and multiplex (copy and repeat) those channels on their outgoing RF and IP channels: It’s WAY more cost-effective and less troublesome! So they have to pay a retransmission fee: Big deal! What will the cost be now to Aereo in dropped subscriptions, not to mention bad publicity from these service problems?
Second, I’ll bet that more than a few Aereo subscribers could actually pick up the HD broadcasts from New York City stations if they tried. Over the years, I’ve tested numerous indoor TV antennas and there have been some real winners out there like the Mohu Leaf Ultimate series and Winegard’s amplified FlatWave antenna.
Both are reasonably priced and perform adequately on VHF channels and very well on UHF channels, which in New York City means you can also use them to watch WNBC, WCBS, and WNYW among the major networks. (By the way, those are the three networks that carry NFL games in the New York City metro area.)
Third; if you can pick up local TV broadcasts with one of the aforementioned antennas, there are terrestrial DVR products that will let you record those channels, like Channel Master’s new DVR+. It has dual tuners, built-in capacity for about 2 hours of HD recording (expandable with any external hard drives or solid state drives through USB ports), plus Wi-Fi connectivity and support for Internet video services like Vudu.
Or you can pick up one of Hauppauge’s WinTV receivers that plug directly into a USB port on your computer and provide terrestrial digital TV reception, letting you use your hard drive as a DVR. I carry around a few of the Hauppauge Aero-M stick receivers and a Mohu Leaf for reception on the road, and they work great.
We’ll never know the actual reason for Aereo’s system failures during the Golden Globes and Oscars, but it’s entirely possible that the company was too clever for its own good by engineering and building a system that was designed to neatly parse and side-step copyright laws.
It’s funny how the law of unintended consequences works, isn’t it?
Nothing Lasts Forever

Earlier this week at an investor conference sponsored by UBS in New York City, the chief executive of Liberty Media decried the rising cost of sports programming on pay television. And he may have inadvertently lifted the cover on Pandora’s Box by doing so.
Greg Maffei was quoted in the Wall Street Journal as saying that the average $4.69 per household subscription fee for ESPN and all of its affiliated networks amounted to “a tax on every American household” and asked, “what happens to the bundle of cable if you keep pushing [the price] higher and higher?”
He’s not alone in wondering if Americans are reaching the breaking point with ever-escalating costs of pay television. There is no question that a small segment of the population is disconnecting from pay TV services and opting instead to keep broadband connections only. This movement is 100% driven by cost – the average tab for a digital TV package of channels, voice over IP, and broadband now exceeds $150 on many cable systems. That’s $1,800 a year!
To put things in perspective, the average subscription (retransmission) fee for cable networks is about what it costs you to park for an hour at a meter – 26 cents.
Viacom’s CEO Philippe Dauman also put the spotlight directly on ESPN for driving pay TV costs through the roof. He stated that ESPN by itself in many systems costs twice as much as of all their own networks combined.
The problem with rising costs for ESPN is that it usually comes as part of a bundle. Yet, many American viewers have little or no interest in sports programming, at least not to the extent that they need a 24/7 ‘fix’ of scores, talk shows, and specials.
Those rising charges are driven mostly by deals that ESPN has negotiated directly with major sports leagues. For example, the Bristol, CT-based network has also managed to get exclusive broadcast rights to the major college football bowl games (the Bowl Championship Series), taking them away from their traditional homes on free broadcast networks.
More than one pay TV system operator has speculated out loud that sports channels could soon migrate to premium tiers instead of being bundled with basic or extended digital channel packages. That would in turn allow pay TV MSOs to lower prices on TV channel packages, which are increasingly seen by futurists as ‘obsolete’ with the increased penetration of high-speed Internet access, the use of DVRs, and the growth in streaming services like Netflix.
Until the past year or so, cable and satellite TV executives were mum on the issue of ever-escalating monthly service charges. Now, one of the culprits has been called out, and it will be interesting to see if MSOs will make noise about moving ESPN and other costly sports networks like Fox to add-on tiers where HBO and Showtime currently reside.
In the meantime, you can still watch plenty of sports for free over the air, including (but not limited to) NFL games on CBS, Fox, and NBC, major league baseball on Fox and local stations, the NBA finals on ABC, college football on CBS, NBC, and ABC, golf and tennis on all the major channels, the NCAA basketball men’s and women’s tournaments and selected games on CBS and ABC, and of course next year’s Olympics on NBC.
Enjoy them while you still can…
