I have just finish installing a Winegard Trav'ler Directv SWM Slimline Antenna on the roof of our 2015 Landmark. I found all of the cables behind a dummy outlet cover in the bedroom on the ceiling. I hooked up all the cables to the antenna an it works just fine. I then ran a cable from the splitter on the roof to the power inverter inside the RV then to the Directv receiver to test for a signal and the test was a success with a great picture on my TV. My question is where does the coaxial cables that where in the ceiling of the bedroom originate from is it in the universal docking station and if so is that why I need to install a RG-6 jumper to get a sattellite signal to my receiver.
