You don't have to use a narrow beam antenna with maximum gain on axis. You can always design it with a bowl-shaped pattern that increases gain toward the edges and lowers it in the middle.
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...
