I had DirecTv wire my travel trailer just as they would if it were a house. The SAT connection on the outside above the CABLE connection runs through my trailer with no splitters to the TV cabinet/swivel in my bedroom/living room. In this cabinet is where my H25 receiver resides. There is a good bit of dead space in this wall which allowed for all of my other feeds to come together and connect to the splitter here, sight unseen. The power inserter was installed at the other end of my trailer in the bunk house where I have the DVR receiver. I also have a line that runs to where my TV hangs outside under the awning. I use my H25 receiver here if I want to watch outside. The wiring to get to the rear and to the side was done beneath the trailer, strapped to the frame. The installation by DirecTv cost me nothing.
When I get to my site, all I have to do is run a cable from the SAT connection on the outside to wherever I put my Slimline dish and once I'm tuned in I have HD DirecTv ready to go at four different locations.
I use the heavy duty tripod setup from
www.tv4RV.com which makes setup a breeze.
