I have a Sirius radio as well. I take the radio head from the truck and install it into the home base receptacle. Hook up the out put from the Sirius radio head into the aux input of the Jensen DVD radio player in the trailer. Since the unit is close to the door I run my home radio antenna, which over 20 ft, thought the doorway. The antenna wire is small enough that both the screen and out side door close tightly. I place the antenna puck either on the propane tank cover on the front or on the rear bumper...depending signal strength ....sometimes the signal is not always full bars..but I do get my "classic rewind" and classic vinyl " and " book radio" channels. I do not like to drill holes into the roof or the sides of the trailer. This set up works for me.
Just my 2 bits worth.
