I pulled an install off the internet from dish and I am a bit confused. The order says a 622 and a 500 pointed at 110,119 and a wing at the 61.5. Can I use a 722 and a 1000.4 dish instead? or a 622 and a 1000.4? there is 1 HD local channel on the 61.5. The customer does not want 2 dishes on their house.
