So I found the site broadcasting LTE 800 in downtown Winchester. It's at 39.185328, -78.165876. This site is not listed on any of the maps here. This does appear to be a new site, looking at the satellite images from 2011 it does not appear to be on the rooftop back then. I'm supposed to be working right up the road from there tomorrow, I'll try to get some more info on it then.
