We have a 2018 Keystone Bullet. It is wired for Over The Air TV and Cable TV. The connection for the service is on the rear of the trailer. There is also a connection under the awning for an outdoor TV (not yet used). Inside is the TV that came with the trailer. It is connected via coaxial cable that comes from the wall - the same 'box' that contains the signal booster switch. just above that box is another that just has a short cable pigtail that goes in a "U" from one connection to another. I've attached a picture.
My question is regarding hooking up a Dish satellite antenna. I tried connecting it to the external connection at the rear of the trailer with the signal booster OFF. It would not communicate with the receiver in the trailer. Any ideas? How have you connected your satellite antenna to your receiver?
