Yes, selected antenna on the TV and scanned channels. Actually have a small TV in the bunk room and tried it there as well making sure it was not the TV. The jack that has the amp button is in the ceiling of the main bedroom so I have not pulled that down yet to check connections, and I'm not 100% sure where the connection is on the antenna itself. Previous campers had the crank up and rotate type where you could see the cable and antenna. Had to fix multiple connectors over the years. No media switcher.
Thanks for the replies!
