ClamLover,
I am sad to say that it looks like you can only hope for two stations. KCPQ and KTBW. KCPQ is currently feeding local news and Fox network programing on VC13.1 and their 24/7 weather channel on VC13.2. KTBW is a Christian station. They feed five virtual channels,(20.1 - 20.5) TBN network, The Church Channel, JCTV, Enlance TBN (Spanish), and Smile of a Child.
If I were climbing that far, I would use the Winegard HD 7698P.
I don't know if you have more than one tree to consider using... If you do, use this tool
