Hello again,
Back again with my update.

So, I had already returned the first Radio Shack antenna mentioned above, and picked up the loop/rabbit ears amplified antenna that the guy there said I should try. He didn't have the amplified one in stock the first time, but said they'd have it in the next day, and if the un-amplified one didn't work, that I should exchange it for the amplified one, and try that. This is the amplified antenna. It's basically the same, loop and ears. It has no 'tuning knob', but has a power cord (for the amplifier):
RadioShack® Amplified HDTV Antenna
Model: 15-254 | Catalog #: 15-254 $34.99

Turn on and tune in.
Upgrade your old rabbit ears with this HDTV compatible amplified antenna. Its designed to capture both UHF and VHF signals (channels 2 to 69) while extending the reception range for all local HDTV broadcasts. It provides signal amplification up to 22 db and connects to your TV with one simple cable.
* 22 dB amplification provids a clear signal, even in remote locations
* Gold-plated "F" connector output for better signal and picture
* 180° rotation to allow fine tuning
The results were the same. Switching around the loop and ears didn't pick up Fox, CW, or PBS (or MyTV). I did receive, very well, ABC, NBC, and CBS. And Daystar came in with snow. Here is the new TV Fool report, using the 'Maps' click, and 20 ft for the antenna height:

Do you think a different kind of indoor antenna is what I need? Or, possibly, could the TV tuner have anything to do with the results? This is not a high-end tv. It's a Dynex (Best Buy's in-house brand) 19" LCD flat panel tv/dvd combo:

Again, I appreciate the help very much
