The discussion is more about rotational torque on the mast and rotator
than a worry about a tower falling down. Think of it as an academic
exercise.

Guys, I really got to wonder about this. It seems to me IF your antenna load on
the tower is a concern, why not just add some guy wires. A guyed tower can
handle the wind forces so much better and you can sleep well at night knowing
that. I personally have wondered about the integrity of free standing towers
over time. Sure, they may look nicer (maybe) and have a smaller footprint
outside the concrete base, but knowing how us hams always want bigger and
better antennas, why not just guy a tower to make sure it will stand up to the
wind forces. Maybe won't handle a tornado but then what tower would?
Just my $.02 worth.

Seems like if the wind is in-line with the booms, there will be a small
amount of torque even if the antennas are perfectly wind balanced (if
they share the same side of the mast).
And that small torque will be somewhat canceled if they are on opposite
sides of the mast.

I'm with you, Chuck. The torque is additive regardless of which side of the
mast the antenna(s) are on.

Maybe I’m dense, but I don’t see how this does anything (much). If the
back of both antennas has a larger wind area than the front, the torque on
the mast is going to twist the mast in the same direction no matter to
which side it is attached.
