I have a U8000 with AP-8700 preamp and can get KTEN fairly well with some careful aiming. I can't get KXII or K35CU though even though they're closer.
All 3 stations are in purple fringe area so I know its a longshot with any of them.

Everything in green and yellow zone I can get no problem, I don't even have to worry about the direction I point my antenna for those.
