[TowerTalk] Clanking Tail Twister II

[Hans Oortman]

Exactly, all Yaesu rotators have planetary gears. Create rotators are
rotators with worm gears and there for make no noise. I have and still use
Create rotors in my tower to turn HF beams with booms in excess of 6 mtrs
and weighing more than 50kgs and never had a problem with them.
