Probably not - The SAT RCVR will need to send a DC CONTROL to the SAT DISH over the RG coax line.
The best way we found was to run a RG cable from the dish separately into the trailer and connect to the SAT RCVR we brought with us from home on our DIRECTV acct. Then we run VIDEO OUTPUT cables from the SAT RCVR to the VIDEO INPUT channel on the TV set.
This way we can use our inside TV set with the SAT RCVR to pick up standard satellite TV channels or the OTA roof antenna to pick up the NATL BROADCAST TV channels by just pushing the buttons on the TV REMOTE...
We never had any luck trying to use the CABLE CONNECTION to hookup the SAT TV stuff...
