One note about
TVFool. I've received a few PMs asking where to click on to check approximate distance from broadcast towers. The link is labled as "Click Here" on the main page of TVFool which is shown in the picture below:
Clicking on that link will bring you to the
TVFool Signal Locator where you can enter your address and receive a detailed analysis of which digital channels are in UHF or VHF frequencies, a list of available Digital TV channels (sorted by strongest to weakest in range), and
azimuth.
