The camper is a new Apex. We picked it up about six weeks ago and it was very cold that day. The only thing we could check to see if it worked was the heater. We should just take it back and let the dealer figure it out. I took a small TV out to the outside connection and scanned for channel. It found seven. Took the same TV into the bedroom and got no signal. Looks like ScottG might be on to something. Cable ends look like the push on type and I don't know if they pulled back the shielded portion. Thanks for all the good ideas. Think it's going back to the dealer.
