I used to have a Channel Master with AMP back in the day before Cable & Satelite broadcasted the local channels in HD; best HD picture I have seen was with my OTA antenna. Blew away both cable and Direct TV. It's in storage now as the locals are now included and live in an HOA - too many antennas up there already. With the new MPEG 4 with direct TV, picture appears almost as good as the OTA (assuming I remember correctly).
