I'm in Greeley, and I pick up 50 channels with a pretty small Terk HDTVO. It fit on my old Dish mast. Might be an option. It is considerably smaller than anything my neighbors have. But my signal isn't as strong as I would like, but it does come with a preamp (12 db). I may get a bigger one, depending on the results from my post in the same forum.
