Hi Jon,
I've had similar problems with my HyGain tribander, and I believe vibration has
something (if not everything) to do with it. Whenever I have a nut/lockwasher
fall off I replace it with a stainless nylock nut. I've never had one of them
come loose. Also, I have never had a hose clamp come loose either. The worm
drive makes them pretty secure. I also believe they are slightly less wind
load (unless you use one too large for the tube size).
