Anyone know of any websites that can assist you in finding out if you can use an antenna at your location for over-the-air HDTV broadcasts??? HomeTheaterMagazine suggests: www.antennaweb.org - yet I keep getting a "cannot display page" error. (Will continue to try - maybe server down at this ungodly hour of the morning.) I live in the Western Carolina mountains and plan to purchase an HDTV. I plan to install an antenna to pick up terrestrial broadcasts as well as to subscribe to DirecTV. I'd hate to invest $$$ in all that hardware upfront, just to find out that an HD signal won't reach my house.
