Ok forget my last post, I found this on the HL forum:
I just paid $75 for a service call to figure out how to make SAT TV work in my 2014 Cyclone that is wired for cable, SAT, and antenna. You would think this would be better labeled at the connections or explained in a manual since many of us campers prefer satellite service moving around as much as we do. My Direct TV guy took out a splitter behind the removable panel access in the basement that allows access to the backside of the incoming utilities connection -universal docking station? He said this splitter was not compatible with satellite (maybe because I have HD dish). He installed a new compatible splitter $15. He ended up using a gray cable that goes to the bedroom from the cable connection as a primary satellite signal directly to the bedroom. He moved the landing of the gray cable from the bedroom antenna to the bedroom satellite connector. i believe he told me that there were NO cables connected to the satellite connection in the bedroom. That receiver then back feeds the rest of the camper to display the same channel as is on the TV in bedroom. I have on the new splitter primary SAT to living room so I can run HD on my liv room TV on a separate HD receiver (existing original installed cable). He said he could put another splitter/distribution connector up by the HD liv room TV and it could back feed the other TVs to display the same channel as on the liv room TV to rest of coach. I currently prefer to have independent HD service in liv room. Since I have limited knowledge of how to best set up this system, I chose to pay the expert ( on my last four RVs). At the price we pay for brand new campers, you would think you would be able to just hook up at outside location and have it work, but maybe I expect too much. Good luck.
