I've installed 2 MonstIRs and they both used the Orion 2800 rotator with
a pinned mast clamp/mast. In the last windstorm, they both started turning.
I used an SAE graded bolt for pinning them both and they both broke. I'm
going to replace the mast pin with a bigger bolt but I'd like to come up with
additional way to keep it from coming loose.
Tom, K5RC, has come out with the SlippNot for Hy-Gain type rotators
that's adds additional holding power to the rotator/mast connection - sort of
belt-and-suspenders approach. That's the direction I'd like to head in. Does
anyone have any additional suggestions? I'd appreciate it.
BTW my experience with M2 Orion rotators is that over the years, just
about 100% of the mast clamps have eventually loosened up. After much research
and investigation, I attribute it to bolt stretch; particularly since nothing
you do to the nuts (LokTite, double-nutting, etc.) seems to help.
