We do have a similar "table mat" style antenna, which cost us about that, and it works reasonably well for stations with nearby transmitters, which seems to mean about 10-15 miles, or less if there are hills in the way.

With it being digital, you either have sound and a good picture, or nothing, but as you hinted, it is hard to go too far wrong for $20.

I have one although I rarely use it as I have satellite.

It works fairly well. Receives the local affiliates of CBS, NBC, PBS etc. Don't listen to the 300+ channel BS. We're about 60 miles from the main transmitters and get about 25 channels. Some channels are a bit flaky and cut in and out particularly in bad weather. With digital, you don't get a bad picture, it's either excellent HD or nothing.
You also won't get any of the traditional cable channels such as CNN, ESPN, Discovery etc.

Florida must be flatter than my part of NC.
