I use a Winegard 9095P UHF antenna with a Winegard AP-8700 pre-amp. I receive DTV signals for ABC, FOX, NBC, TBS-17, CBS, WB-36, UPN-69, WHSG-63, and WTHC-42 ("The Atlanta Channel"). I live in Stone Mountain and get between 80% and 96% on all DTV channels, except 42 (I get 65%).
I do not pick up the DTV signal of PAX because they are about 120 degrees in the wrong direction. As an experiment, I hooked up an indoor UHF antenna and did receive PAX's DTV signal.
I am awaiting the delivery of Sony's new KD-34XBR960 TV with built-in HD tuner to see if I can pick up additional DTV channels (from Macon).
