We purchased our Nomad 21' TT in March. It has a wall jack set up with 2 coaxil cable ports. The top one has a button beside it to turn on the digital antenna. The other one goes...no where! I called ...
I believe the other one is connected to the back of the trailer for cable at a rv park. How do you know it goes no where did you remove the plate? If so disregard. Plus a $100. sounds cheap and if anything goes wrong it's on them Mike
