[TowerTalk] yaesu rotors

[Bob Maser]

I worked for The quality manufacturer of 10 turn pots and they are still 
fragile, wirewound devices.  If you want the ultimate, why not buy a prop 
pitch rotor and control it with a Green Heron controller.  That's what I am 
putting up and I expect to have zero problems with it, regardless of what 
antenna(s) I put on it.
