I never used it or a TV in side the whole time I have owned it, the antenna came with the camper- I would not have ordered it given the option.
At this point I am not going to install anything. The camper is on the market- I will include it in any sale but off to the side...I will let the next owner choose what to put in it's place.
The coax was starting to break down and I took it off because of that as well that it is pain in the butt sweeping snow off the roof with this thing in the way- I should have taken it off years ago.
