Well the Cornet F-645A arrived, and I had even worse results
with VHF channel 7 than the Radio Shack UFO. I found the Cornet
flaky. Some of the DTV UHF channels would not even come in
unless the amp/power was turned on, making me think the power
switch actually closes the circuit for the UHF antenna.
Out of curiousity, I tested it out on some analog VHF and UHF
stations, to make sure it was pointed correctly (same towers
as DTV here) and also found the middle 1/3 of the gain knob
actually made the picture worse on the analog signal.
I can only assume that wasn't helping the DTV signals either.
Out of curiousity, I took it apart to see how it was built, and
found the wires that connect the antenna elements (rabbit ears
and UHF loop) are about as thin as you can get. Note in the pictures
those connecting wires are thinner than the LED wires!
There is actually circuitry in there, but I'm not sure it is better
than a non-amplified signal.


In the end, I ended up making my own antenna, and guess what?
It worked great! It looks ugly, but cost me under $3, and it pulls in VHF-7 with 68% signal strength and 100% quality (APEX CECB has dual meters)
I hope this helps someone out there!

How to build an indoor VHF antenna
When I was comparing various antennas, I found the Terk HDTVa to be superior to most others I've tried. The VHF dipoles are thicker and longer than most other antennas. However, the UHF reception is a little too directional for most people's taste.
The following page at HDTV Primer is a great resource for comparing various antennas including the Sharp Shooter.
Comparing some commercially available antennas
The Sharp Shooter was one of the many antennas I've tried, and I wasn't particularly impressed with it. In my opinion, it doesn't perform any better than many other antennas that cost less than half as much.
