Thanks for the response. I have a 2008 Hornet FKS. It is not preped for sat.
I took the plate off when I first bought it and took off one of three cables from the tv hook up and added a new coax plate and hooked that coax to the new plate. The satellite now comes through the cable port but does not go to the bedroom. I would like to get it to do that. Was better than drilling through the outside and still wouldn't go to the bedroom. I don't remember seeing a splitter but it has been a couple of years. I will look again. I am thinking that the splitter is the tv plate and when the amp. is off it allows the park cable to come through. That would go to all tv's. Satellite needs to travel back and forth through the cable and can't do that through the tv antenna plate.
Thanks again.
