Re: Satellite hookup
Do you have two TV sets and a splitter between the cable connection and the TV sets to allow both to share the cable from the RV park? If you do, the splitter is the problem. A signal splitter will not allow the 19V power for the dish LNB's to pass through it. In order to use a splitter it has to be between the receiver and the TV sets. It can't be between the receiver and the dish.
If this is what you have you will have to install a separate coaxial cable for the dish, or remove the splitter and that will mean that one TV will not work.
