I have a bat wing on the roof, with a boost inside the coach. It kinda works, but not all that great. Also have a satellite on the roof that does nothing & nobody around here knows anything about it...
I do a search on the TV with the bat wing antenna, on boost. At home I might get 30 channels. At the camp grounds.......not so much. I added that thing to the bat wing that helps with digital.
I have a Winegard satellite dish.....Road Trip SD. I bought a new power supply from Winegard. You can hear & see it looking for the satellite.
