I don't have any experience with the M2 antennas, Dave, but it sounds as though
the problem isn't that the set screws themselves are backing out; rather
the material they are supposed to lock in place is crushing with vibration,
and this is allowing the joint to become loose. Can you do something to
prevent this crushing, like add a piece of harder metal at the contact
point to spread the load?
Or just Heliarc it...
