I don't have a rotor, so my only vibrations are from residual earth quake vibrations in California that make it to Texas (i.e. not many).
Still, I think I'll ensure it has smooth edges the next time I'm up there piddling around.
Also, AFAIK a top rail from a chain link fence works just as good as a "real" antenna pole, and is cheaper because it isn't a specialty item.
