[TowerTalk] What is a good way to rotate a tower?

[Peter Sundberg]

My good friend Doug, VK3UM uses a ring gear from a Centurion tank at the
base of his tower supporting a 30' dish. The gear is 7' in diameter and
rotates very smoothly with the original 28VDC motor/gearbox assembly. There
is no backlash at all and with PWM control of the motor rotation speed is
easily controlled. Doug's hilltop installation has survived a number of
storms without problems despite the 30' Kennedy dish catching wind at the
top of the tower.

I see no problem putting a self supporting HF tower on such a ring gear and
then rotate the whole thing. 

The guy in VK3 who sold the ring gear to Doug had another 5 of them tucked
away in his garage when we were there.... pity they sit so far away from SM2..
