Baj when I first got my trailer it had an antenna and I said I would never have a TV in my trailer so took it off - in the place where the hole was - right over the table/bed I made the hole bigger and added a maxi fan. Which I love. I did leave all the wiring etc for the TV jacks in place though - glad I did as I added a TV last year - but now I'm sorry I dont have an antenna as I can only use the TV on its own when at a camp ground with cable or to watch movies. Purchased a small portable antenna to try out but not a lot of joy with it. Depending on what type of antenna you have on your Scamp
you might want to take a look at the Camping World website as they may have a newer part you can add onto or replace the old one with that may work better than what you have.
