I recently got Dish network and have a question regarding the locals in HD. I have an off-air antenna and receive HD for ABC, CBS, NBC, UPN, etc but not Fox. Fox is received on the dish but not in HD. My understanding is you have to get the HD locals in HD using an off-air antenna. I can't get Fox on the off-air antenna. I called Fox and they said they broadcast in HD over the air, I should get it on their digital channel #42. I can't pick this up. Dish takes no responsibility. Any ideas?
