As for the person who said "Pretty much a decoration" In parts of this country Television Reception has always been .. Difficult, (Less you had Sat TV) I mean if you could get a signal at all.. It was snowy and possibly distorted.
My parent's 2nd house.. Put a 100' tower in the back yard with Channel Master's best atop it and it worked.. Rather well in fact. but lesser antennas not so much.
Where I'm at with the RV... I get more over the air TV than I can watch. So i am stocking up on movies for when I'm in the land of poor signals.
