Winegard satellite dish RM-DM46

Take a look on the roof at exactly where the cable entry plate is located. Using that location, see if you can translate that into where it might be at the same location inside the coach. If it is near a light fixture, a ceiling speaker, the front cap or a side cabinet you might be able to find the coax on the inside as well or see the run the coax makes. If this is a factory installation is may not be as easy and the run my not be accessible. However, if necessary, you can run a new coax from the antenna, leave the same kind of loop on the roof that's available now to allow rotation, and then run the coax across the roof to any convenient location that allows access to your satellite receiver. This can also be done to add a 2nd coax for a 2nd receiver. Just run the cable as necessary across the roof and use a new cable entry plate to seal up the entry location. You will then want to secure the coax to the roof and this can be done with a dab of Dicor under and over the coax every 6 inches or so along the length of the coax.
