OP here. After posting the question I had some other issues that came up am only just now catching up here on RV.net. Turns out I DO have the old style plate with the little power switch which I never even noticed. I ran setup after turning on that switch and indeed I did get channels, 34, though many did not come in well. I raised the antenna with the crank, and the handle broke off. No big deal, $6 on Amazon, but I couldn't seem to turn the antenna from the inside. It's obvious you pull down the ring around the handle and then turn it, but it wouldn't turn. I got out the ladder and was able to turn iit up top. Can't see any reason why it wouldn't turn from the inside once it was raised beyond the guard. Any ideas?
