[TowerTalk] 4 SQUARE ORIENTATION

My own experience with my 80 meter 4 square would indicate that the
major lobes in the forward direction on the 4 square are really pretty
broad.  In reality, there does not seem to be much of a "null" in
between major lobes in the forward direction.

Performance in between two of the favored directions (like due west on a
4 square that favors NW/NE/SE/SW) does not seem to suffer.  I sure have
no problems here in the midwest working VK or Africa on 80 mtrs.
However, it's not unusual to have the morning paths looking west
frequently favor the SW antenna, sometimes even as far north as JA, I
suspect due to the grayline effect.
