I live in a bottom, surrounded by hills and trees, in a fringe reception area. My digital TV reception stinks to put it mildly. What is the best kind of antenna to get, where can I get it, how high should I mount it, what is the best way to mount it etc. ? I live in a small wood house with a chimney, and a tin roof. By the way, I am not cheap, just broke and don't make a lot of money, so the cheaper the better. Thanks?
