The antenna on the RV is kinda minimalist, something like a
Winegard Sensar. It's supposed to pick up VHF, FM & UHF and has a built in 12v signal booster. They really don't supply specs, or say it will pick up anything. They just say "crank it up and aim it."
A channel scan with the boost off yields fewer channels, and the channels are hard to view- analog and digital. Boost on improves things tremendously. But not quite enough to watch a digital signal.
I'm trying to figure if the problem is the trees, or hills between me and the towers, or both. I guess I'll just have to blow the $75 bucks on a 5' tripod for the shed roof, with a 5' pole, and another $50 on the antenna. That should put the antenna up a little higher than the antenna on the RV.
If it's the hills, I might spend a big chunk of change on a tower and still not get much.
