the short answer: NO, the term Cable/TV indicates exactly what it's for - the outside signal from a campground CABLE in to your TV.
Satellite signals require a 'two way' powered routing, and therefore most any 'standard' cable/tv wiring will not allow for it.
The easiest way we've all found our satellite signal is the always run a dedicated coax cable DIRECTLY from the antenna to the receiver, however you choose to do that. Some will use a simple open window, others will find a slide seal to rout it thru, or even a roof entry thru a plumbing pipe chase.
If your coax connection on the outside of your RV does not say 'SATELLITE', then no, it's not designed for a satellite signal.
