Subject: Rope or not.... K7LXC's query
Author: Pete Smith <n4zr@contesting.com>

Seems like a fair question. I'm not aware that existing mechanical design
software addresses the question of resonance, fatigue cracking, etc. How
can Force 12 be sure that thin end sections of elements will not fail under
high wind stress over a period of time? I'm not surprised that this
problem would turn up first in the D or H models, given the extreme
conditions they are designed for and the relatively small number of
antennas built to these specs.

Rope damping may not be the answer, but I'm not persuaded that the
designers necessarily have all the answers either.
