Like Tom, we use Dish and a Pathway X2. We didn't need a satellite feed to the bedroom, so I installed a separate coax connector in the wall of the slide with the TV in it. That way we have no issue with the configuration of the factory coax wiring and splitters. Here's what's on the outside of my slide wall. I just made a short coax cable and connected it between the exterior inlet and a regular coax faceplate inside behind the TV. The Pathway II is a bit sensitive to coax length, so this also solved that by not wandering around though out the OEM routing inside the fiver's walls.
