Never said they would.  I was responding to Gary.

I guarantee that those articles are not going to say anything about winds that rotate.  There is no such thing as "aerodynamic balancing" in the case of rotating winds.  Anything you add to the structure in an attempt to do so simply adds to the problem.

I truly do not see how this is so difficult to understand.  It's high school physics.

I have from time to time seen it professed that mounting two antennas on
opposite sides of the mast will equalize the torque supplied by wind.

The only thing mounting on opposite sides of the mast will do is equalize
GRAVITY forces on the mast (that try to bend it over) which will be rather
small differences given only a few inches distance apart.

Torque is rotational. Both antennas are going to exert the same amount of
torque no matter which side of the mast they are on.
What am I missing here?
