I had good FM reception using a Y5-7-13 mounted outside. Some times having an antenna outside high up, even off band, is better than having a properly tuned antenna inside.
You should try a vertically polarized FM antenna. KSAN has 8.9 kW ERP horizontal and 8.9 kW ERP vertical. KSAN-FM1 has 0.185 kW ERP horizontal and 0 kW ERP vertical according to the FCC database. Other than signal cross polarized by bouncing off stuff, the booster should not be doing anything vertically polarized.
Channelmaster has an FM antenna with a vertical mount on it.
http://www.channelmasterstore.com/Ma..._p/cm-3026.htm If you mount a yagi vertically, a fiberglass mast (or something strong non conducting) would be good to prevent a metal mast from changing the pattern.
KITS is a bit more of a mess. The FCC database shows 4 boosters for it. Of those, 1, 2 and 3 are all only horizontally polarized. KITS-FM4 is vertically polarized. KITS-FM4 does not show up on your plot, and looking at the power spectrum at the bottom of the plot, it is probably below -100 dBm at your location.
So, if I were you, I would get the channelmaster vertical FM Yagi and a section of fiberglass mast, put it up on the roof, point it at 337 degrees True, and see what happens.
