I ran 2 different scenarios in your situation using TVfool, and neither one looked promising at all: you have large mountains around you and no close-by TV stations. I am not at all sure that a TV antenna is a good investment for you: you have the prospect of one network TV station in your area if you invest in a large outdoor antenna. My best suggestion would be to consider using a satellite service or cable TV if it is available.

Here is a listing of your available TV based on the coordinates that you provided to me. This information comes from http://www.TVFool.com

It is accepted that you need an nM (noise margin) of "0" or better in order to see a digital TV signal. You'll see that your listing has no stations that approach that signal level. I wish that I had better news.
