You of course would have to convert his replaced SAT RCVR to your SATELLITE TV ACCOUNT etc...
We did this all the time before Digital NATL BORADCAST TV came out. Ran a RG Cable from one of the SAT DISH connections to a SAT TV RCVR. Then ran VIDEO cables out of the SAT RCVR to the trailer VIDEO INPUT connection. Actually did the same thing going to a second SAT RCVR in the Bedroom area.
This gave us standard mode SAT TV in both areas to use from the one PORTABLE SAT DISH which had two ports coming from it.
When the digital NATL BROADCAST TV came out we finally stopped bringing along the SAT TV stuff and just use the OTA BATWING roof TV antenna to pick up full blown high def TV from the NATL BROADCAST NETWORK free to use. HDTV was much better to watch and all we watch is NCIS and WX/NEWS/24-7 Local Radar anyway...
