When I had my hopper installed, the tech said he could reposition my dish to pic up the eastern arc, but I'd need to set up a new ticket. He had a good line of sight. I just wanted to check that I'd get all my channels. I have a 110, 119, 129 setup now. The 129 is a PITA. Its on the ground going though a switch, and is a weak signal, so I'd rather have the eastern arc if it a win win. Are there any drawbacks?
