I am planning on getting a directv satellite system soon, so I will be able to get NFL Sunday Ticket. And in the near future setting up a home movie theater with HDTV. I have a antenna in my attic, but will it be more worth while to buy the Oval dish instead of relying on antenna. It still works pretty while and I know its pretty big. But will the oval dish be easier and less of a hassle, I would appreciate your comments thank you
