I'm no help with this as I have yet to figure out our system. Inside, we have the switch box with antenna-cable-sat/aux and wire in from each and a TV out cable (total of 4 cables from the back of the box). In the same storage area (next to the TV) is a totally separate bundle of wires taped together with a "satellite" label. There are no ends...just raw hacked off wires. I cannot find a separate "sat-in" receptacle on the outside of the coach anywhere. In the storage bin where the electric is, there is a "park-cable in" and in a bin on the other side of the coach is another "park-cable in".
I can't find anyway to put the receiver inside so it feeds the TVs from there. We can get sat TV only if the receiver is located outside and the "out from TV" on it goes into the "park cable" receptacle outside. Of course, that makes changing the channel a challenge from the inside! It's not that we HAVE to have TV. It has become more of a battle of wills and right now the wiring is winning.
I hoped someone reading this thread might have the answer! I can't figure out why the wiring is there and apparently separate from the wiring that's hooked up but there's no outside plug in nor a way to attach to the receiver.
(We're using a Winegard Carryout.)
