This is our first real time out with our 369RL. Everything has gone well with one exception. We are unable to watch TV in the bedroom. We are in a campground w/o cable. The antenna is up, the booster is on and the TV in the living room is working as expected. The bedroom TV input is set to TV but the screen is blank with the words low digital signal. Swapped the coax antenna to the other coax on the ceiling plate with no results. What am I missing?
