In my 2012 Rushmore, 35CK, I found a coax connection between a "blank" or unused connector behind the TV set and another "blank" connector in the bedroom. An ohm meter verified the connection so I connected my satellite receiver to that connector behind the TV then moved the input wire in the bedroom from the antenna to the "blank". Works like a champ now. Just need to move the wire back in the bedroom when not using satellite and a quick connector makes that easy to do.
Hope that makes sense.
