I've got a 2021 Reflection 31MB and attempted to plug in my satellite dish at the docking station. No connection. I then by-passed the docking port connection and ran the cable through the door and plugged into my Direct TV box and it worked fine. I removed some of the paneling in the basement and checked all of the connections that looked like cable TV. The wiring down there looks like a mess, wires, cables, and hoses just stuffed behind the paneling. Very sloppy installation. Anyway I found several TV cable connections that were a little loose but it still failed to make a connection with my dish. I ended up shoving the cable through the slide out and plugged it into the box and it worked fine for the weekend. I hate to take it into the dealer for one item so maybe someone out there had the same problem and could pass on any tips to trace down the problem.
