Re-reading your thread from 2012, I see you brought up the issue of getting an NBC affiliate.
Per rabbitears.info, W27AU carries 'NBC' and 'Antenna TV' networks, so the HD7694P should get all the major networks for you.

I should emphasize the importance of mounting so as to avoid aiming through obstructions such as trees and nearby structures. (Oops, I see you're already are aware of that... we posted at nearly the same time.)
