Not having it straight up or down will reduce the received signal strength (for each of you) by the square of the cosine of the angle by which it deviates from being parallel to the other guy's antenna. If the "other guy" is a repeater, his antenna almost always points straight up.

Ummm -- perhaps you meant rotating it about a vertical axis. No, that won't do squat.
