By the time the tower rotates far enough to have the torque arms
do any good you have already used up most of the allowable lattice
strength. Commercial installations don't use "torque arms" as hams
do, they use things like the TA25 Torque Arm Stabilizer to get 6 guys
to 3 anchors. Only the ones they use fasten onto the tower a lot
better than the TA25 does and have more iron in them.
Lots of commercial installations have 8 and 12 foot dishes side mounted
to a tower, but they use the six guys to take up the torsional load
and not feed it into the whole tower length.
