SCVJeff - Thank you for your clarification, but I must be a little dense. If all I know is that I am camping tonight at Harlan County Lake near Republican City, how do I know which way to turn the antenna? Tomorrow, I will be anywhere from 200 to 400 miles west of here. When I don't have access to the internet, what do I do? Never have that problem with analog signals. If I get out my trusty map, I do not know where the closest towers might be located. Maybe "Rand McNally" will start putting digital TV tower locations on their maps.
I guess, I could call someone that is at home, ask them to enter a location on this site and then get back to me. :h
