My conclusions are rivets are a *very* poor method of
securing elements, and antennas need dampers inside
elements.

Hi Tom --
Rivets seem to work ok in lots of important structures. I think the
problems are not in riveting per se, but rather the
engineering of the riveting system (i.e., proper sizes, material, location and
quantity)?
I agree with you on anti-vibration. Most thin elements need vibration
dampeners. The method of assembly has no impact on
whether the assembled element will exhibit mechanical resonances in a breeze.
