get satellite signal in

There are a lot of different wiring configurations in RVs. Mine originally had a single coax input setup for cable. No dedicated sat input. But that coax came into a dual coax wall plate near the TV. And there was a short coax jumper cable between the two connectors on the wall plate. I could leave the jumper on if I connected to cable. Or remove the jumper and connect a short coax cable from the wall plate to my sat box for satellite. That worked fine.

But I tired of messing with the jumper and added a new external coax connector connected to a new inside wall plate dedicated to satellite.
