I never could figure it out without tearing up everything tryig to use the SAT connection that is next to the CABLE connection on the outside of the trailer. I wouold have to unhook things to make mine work so I just run two RG cables in from the two ports on the portable SAT DISH - one to the bedroom area and the other to the living room area. Then I connected each RG cable to a SAT RCVR ANT input. Each SAT RCVR picked up the SAT DISH just fine doing it this way. Then I used the VIDEO OUTPUTs of the SAT RCVRs and ran that to a VIDEO INPUT on the HDTV in each room. This way I can select to watch the regular CABLE/OTA TV or the SAT TV using the TV remote. Of course when I selected the SAT TV I would have to switch remotes to change the channels...
Worked out great for us but when the digital NATL BROADCAST local HDTV came along recently it turned out these local broadcast signals were all in full screen high def digital TV mode and much better quality than the SAT TV stuff so we just stopped bringing along the SAT DISH and extra SAT RCVRs from the house. We always like to watch the national broadcast channels anyway and they are FREE of course...
If there was something we wanted to watch on the cable channels when camping off the power grid then just use the computer to watch them.
We even do this when at the regular camp ground sites that have cablehookup. They are all in analog mode so we use the OTA BATWING antenna to watch the locl NATL BROADCAST channels and then switch to to the cable to watch the other stuff... Once you start watching full screen high def digital TV it is hard to switch back hehe...
just my thoughts
