I've tried all kind of ways to get Sat. TV. Ive had domes on top, Winneguard carry out, and now the tailgater. Had a service man that understood all this. All I have to do is set tailgater where it has a clear view, let it run its 15 minute set of things, and we have Sat. just fine. RV came with a Sat inlet plug. Very simple. If we want DVD we just select correct settings in tv and dvd player. All very simple. I never use the bat wing.
