Like Harvard says I don't get DC Control Voltages to pass through the CABLE-SAT labeled connections on the outside of my trailers.
Back in the day when I was using SAT TV I ran my own RG cables through the pass-thru doors to get from my portable DISH tripod usinag a dual head and two SAT RCVRs that I would bring along from my DIRECTV home account. Worked out great for me doing it this way. I connected the SAT RCVRs VIDEO output to the VIDEO INPUT of the HDTVs and then could use the TV remotes to switch between CABLE-OTA-SAT.
Once the NATL BROADCAST SYSTEM went to Digital TV I stopped bringing along my SAT TV items on the trips. Full blown HIGH DEF TV for free was much better using the OTA setup pointing to the local towns...
Have no idea how the newer TV setups are operated these days. Going down the various posts sounds like a very expensive endeavor with all the things you need to purchase to make it all work...
We get our NEWS WX RADAR and NCIS fix just fine when camping off grid using the National Broadcast free network.
