For horizontal polaration on a diamond quad, the feed to the DE should
be at the end of one of the vertical spreaders. If the reflector and
director are assymetrical (e.g., there is a stub at one corner) that
should also be aligned with a vertical spreader. It doesn't matter
whether you choose top or bottom, however.
