We added a fitting inside of the refrigerator area, ran a short wire from that and zip tied it to the outside fridge access door. We set our Dish Playmaker out run the cable from that to our cable at the fridge access door with a barrel connector. Inside the camper we run a cable from that newly installed connector plate to the Dish receiver. At that point my wife is a happy camper.
There is no noticeable loss of signal. There are lots of places the cable plate can be mounted. Pick one and don't look back.
