I put my address in and directv says Grade A and Grade B for ABC, FOX etc, that i will need to put in a waiver to get them and they say " AFFILIATES RARELY GRANT A WAIVER FOR GRADE A SIGNALS. Much of the time, waiver requests for Grade B signals are not granted by affiliates either." Is this true? I live in the middle of know where and can get ABC only with a antenna and it looks like crap. What about getting ABC etc in HD?
