I recently purchased a HD antenna from Radioshack (Brand: Terk, Catalog#:15-1872, Model: HDTVi [sorry, can't post links yet])to receive OTA HD signals. I set it up and I can get NBC, CBS and PBS HD signals just fine. However, I cannot get FOX or ABC HD channels. I believe that both Fox and ABC broadcast in 720p. While reading the box the antenna came in it mentions it is set up to receive 1080i HD signals but I see no reference to 720p. Does this mean I'm out of luck as far as receiving Fox or ABC HD Signals? Does someone know of an antenna that will fit my needs better?
