Winegard’s SS-2000 follows up last years’
introduction of the basic Square Shooter VHF/UHF antenna. What’s
the difference between them? The SS-2000 has a built-in preamplifier.
The original Square Shooter had a rather unique design,
one that could be best described as a ‘flattened’ helical
dipole antenna with a log periodic element shaping. (Completely befuddled
yet?) The benefit of the ‘flattening’ was a more compact
design, while the log periodic construction provided greater bandwidth.
In my original tests of the SS-1000 (http://www.hdtvexpert.com/pages/squareshot.htm),
I found out that its unique design and ability to not only change
azimuth but also its polarization did enhance reception of both VHF
and UHF signals to some degree.
Actually, the SS-1000 was much better at pulling in
UHF stations, given that its comparatively short electrical length
resonates at much higher frequencies than a pair of rabbit ears or
a conventional dipole antenna. My tests with competitive antennas
– all of which sold for much less – showed the SS-1000
to be an average performer in most cases.
The SS-2000 sent here for review is basically the same
antenna, but equipped with an internal VHF/UHF preamplifier system.
You could expect the antenna to perform pretty much the same as the
SS-1000 version, except that weaker signals should be stronger, with
less noise seen on analog stations and more reliable reception of
digital stations.
TEST PROCEDURE
For that reason, I decided for my ‘second look’
to forego outdoor tests – the first review has plenty of examples
of how the SS-2000 behaves in elevated and tilt-polarization modes
– and simply test for indoor signal quality. The indoor environment
is prone to multipath by nature and the SS-1000 did a pretty good
job with indoor reception the first time around.

Figure 1
The test was simple: The SS-2000 and each antenna I
compared it were placed on a counter in the center of my office, next
to a wall. This location has low-to-moderate signal levels and moderate
multipath, which makes it a great place to try out indoor antennas.
And it’s likely that many purchasers of this antenna will mount
it in an attic, perhaps in a similar environment full of signal echoes.
For my comparison antennas, I dug up Radio Shack’s
15-1880 amplified combo VHF/UHF set-top antenna, Zenith’s ZHDTV1
Silver Sensor UHF-only log periodic tabletop / set-top antenna, and
one of my prototype 5-element UHF-only yagis I made about 5 years
ago.

For kicks, I also hooked up a $3.99 Radio Shack UHF
bow-tie antenna, taping it to a small box. Since this antenna, the
ZHDTV1, and my ‘junk box’ UHF yagi don’t have internal
amplifiers, I hooked up a Channel Master Titan 2 #7775 UHF preamplifier
system to each of them when tested.
For reception, I hooked each antenna up to an LG LST-4200A
4th-generation digital TV tuner (it also receives analog NTSC signals),
performed a channel scan, and looked to see how many of the available
local DTV stations were captured into memory. I also kept track of
the number of analog stations that were usable.
Digital TV waveforms were checked with a Sencore SA1501
spectrum analyzer for strength and quality on each channel. Accordingly,
I positioned and oriented each antenna for the best-looking 8VSB waveforms
across the band before performing a channel scan.
RESULTS
The SS-2000 performed pretty much as expected. It locked
up a total of 22 total stations (13 analog and 9 digital) with the
antenna, including all of the major networks. Most of the received
waveforms were clean and any multipath that resulted was in the range
of the 4200’s equalizers.
But the SS-2000 didn’t always produce the strongest
signal on a given channel. Radio Shack’s 15-1880, which did
very well against the SS-1000 indoors, once again trumped the field
of contenders by pulling in 26 total stations and did much better
with VHF signals than the SS-2000.


Figures 5a-b: Winegard’s
SS-2000 did a good job with digital signals from KYW-26
and WGTW-27 (top), but not much better than Radio Shack’s RS-1880
(bottom).
Zenith’s version of the Silver Sensor also flexed
its muscles; grabbing the #2 position with a total of 24 stations
(14 analog, 10 digital) once it was hooked up to the Channel Master
preamp. That’s pretty good performance for a UHF-only antenna!


Figures 6a-b: The $190 SS-2000
received WPPX-31, WPSG-32,
and WYBE-34 quite well (top), but the $3.99 UHF bow tie,
feeding a Channel Master Titan 2 preamp, did almost as well! (bottom)
Surprisingly, Radio Shack’s modest little bow
tie antenna became a real tiger with the Channel Master preamp behind
it, coming in right behind the SS-2000 with a total of 21 stations
(12 analog and 9 digital). My ‘plumber’s special’
5-element UHF yagi, mated with the Channel Master preamp, was good
for fifth place with 20 total stations (12 analog and 8 digital).


Figures 7a-b: Although the 15-1880
provided a strong signal from
WTXF-42, a cleaner 8VSB waveform was seen from the SS-2000.
Of all the antennas in this test, only the SS-2000 and
my prototype UHF yagi could reasonably be considered for outdoor use.
Although the latter can’t be rotated to change its polarity,
I have found it’s not necessary in an outdoor installation –
just aim the antenna for best signal strength, and lock it down.


Figures 8a-b: Zenith’s
Silver Sensor (also feeding the Titan 2 preamp)
was about equal to the SS-2000 with the signal from WPVI-64,
but it bested the Winegard product with reception of WUVP-66 and WCAU-67.
THE VERDICT
The SS-2000 works much like its non-powered cousin and
is most effective at UHF frequencies. Its performance in the high
VHF band (channels 7-13) is average to below average, and I would
not recommend it for low band VHF (channels 2-6) service as it just
doesn’t have enough gain (unless you live within 10 miles or
so of the TV transmitter).
The ability to change polarization is a mixed blessing.
You can solve one multipath problem, but create others by turning
the SS-2000. VHF TV stations use circular polarization to overcome
multipath, but UHF stations use horizontal signal polarization. The
rule of thumb has always been to match the polarization of your receiving
antenna for best results.
If you are going to mount the antenna in an attic, it
pretty much doesn’t matter what kind of antenna you use –
no one will spot it and say ‘hey, that thing is UG-LY!”
In that case, a conventional yagi antenna is always the best choice.
But for outdoor use, you may prefer the more compact, boxy look of
the SS-2000 – it’s about as obtrusive as a DirecTV satellite
dish.
