That's why the quadrifilars work so well. I measured the pattern some 
time back, and the "beam width" is about 140 degrees....

Point them straight up and be satisfied with that part of a pass, or 
mount them at 40 degrees, and rotate AZ with a TV rotor for the 
entire pass. For 50 degree max passes point them at the center of the pass...
