"olly"....we need more info. The Travlr typically comes with three cables as supplied by Winegard. There are two coax cables and one control cable. In a typical installation with one receiver, the coax cable runs directly from the satellite to the receiver. The other cable is stubbed off inside the coach. The control cable runs directly to the sat control box.
I've owned and installed two Travlr's. When I had issues with the signal, I found loosening and then tightening the cable at the satellite base solved the issue.
We need more info, like, does your cable run to connection plates before it reaches the receiver..
