Hmmm... so you mean kinda like the shear pin on my 5-hp trolling motor? I would much prefer a slip-clutch because once the shear pin goes on your antenna system, well it's pretty much a free-wheeling windmill after that!

Okay, as far as the trolling motor goes, it's not a very big a deal as long as you have a paddle onboard and aren't fishing upstream from Niagara Falls!

Hello Al,

Valid questions all. The engineers at Orion would have to provide the 
estimated failure torques for the various parts of their rotator. Where do 
you want the weak link to be? I think most people would prefer it to be in 
controlled slipping of the mast clamps or shearing of a sacrificial external 
pin or key rather than gears inside the rotator.
