Topband: 4SQ antennas directions

Midway between 25 and 55 is 40.

Midway between 310 and 350 is 330.

Rotating counterclockwise 10 degrees from the 45/135/etc common USA
settings would give you NE and NW pattern centers at 35 and 325.

35 and 325 is very close to 40 and 330. It will bring far west USA up from
30 degrees off center lobe (-1 dB) to 20 degrees off center lobe (-0.5 dB),
for a half dB improvement. It's also mildly better for Scandanavia and
Asiatic Russia.

If the orientation is entirely arbitrary, then might as well get the half
dB. They didn't get 45/135/etc from the Bible. It's just the direction to
Europe from my part of the globe.

What gets done about the counterpoise for 160m verticals, excellent vs.
poor, will make far more difference.
