I used the Antenna Selector and I believe I will need at least two antennas. I'm not really sure the right way to do this. I'm including a link to the report I got from TV Fool for my address.

I use a dual tuner HD TIVO to prerecord most of what I watch, so a rotor is out. I have a 20' mast to put up and my house is about 16' tall in a rural area.
I'm primarily interested in the stations located at the antenna farm 12 miles away at 97 degrees and the PBS station at 308 degrees and 28 miles. There are other stations I would like to get at 80 degrees and 54 Degrees that are farther out but not worth getting a third antenna.
I would like to keep the antennas as small as possible because of wind and the signals from the antenna farm (97 degrees) are strong enough I could get them with rabbit ears if my house wasn't sheathed with foil! What should I do?
