Hi Lee,Many towers work just fine without the TA25 assy. My opinion is that it
depends
on what antennas are mounted on the tower. The mass and size of the antennas
and
rotator acceleration/deceleration determine the torque loads. Small light stuff
probably
doesn't need it, big heavy stuff probably does.

I don't totally agree. A bit of the right movement can be helpful (like
rotation on a
pier pin footing). Too much of the wrong movement can break it (like rotation
on a fixed
footing).
