I currently have a hopper connected to a western arc dish and a dish 500 for 61.5 locals via a 4 way switch. I would like to just move to the eastern arc to get rid of the extra dish. In looking at various sites I see 1000.4 eastern arc advertised. These all seem to be gray in color and the new installs I see seem to be using ones that are black. Is the black one's a 1000.4 or something else? Does the hopper work with the 1000.4? Is the black one better for some reason?
