Hi Roger, et. al.,
When the wind really blows, I hold the brake down and let the antenna
rotate by turning the motor to the direction it wishes to be. I then
release the brake lever so the brake is re-engaged. That way the
antenna doesn't tend to more than swing back and forth a quarter of a
turn or so if the mast rotates in the rotor, and I can recalibrate it
without climbing the tower (using the adjustment on the rotor control
box).
73,
