[TowerTalk] New ROTOR design at VISALIA DX convention

[David Gilbert]

Very interesting, but that side mount version bothers me rather a lot.  
No matter how strong the rotator itself may or may not be, I find it 
difficult to believe that a single leg clamp like that wouldn't simply 
twist around on the leg.  People have such problems even when using much 
larger clamping surfaces on two inch diameter masts with less leverage 
than a side mount would have.

Maybe more importantly, the potential rotational torque of a 25 sq ft 
antenna in the vertical plane (36 foot boom trying to act like a 
propeller) would be incredible ... not sure how it wouldn't bend the leg 
of the tower given the roughly seven inch span of the mount.

I really like the stackable mast clamps on the other versions, though 
... that's a pretty neat idea.  Each is independent so the clamping 
forces always add up, and if you need more area you just add more clamps.

73,
Dave   AB7E
