I'm using a radio shack BALUN off the dipole. That's feeding into a VHF/UHF coupler.
I have moved the antana to a window on the east corner of the house. Internal structure shouldn't be an issue.
I haven't modeled it. I got the freq of the station and ran it through the formula on this site:

I'm getting signal numbers from a Linux prog called zap:

Anyway, I'm getting good signal now. I just wondered about the individual dipole wired being front-and-back or top-and-bottom.
