The wind load is small because they use wire elements rather than aluminium.

As hinted in my previous, detuning can be an issue.

I, too, appreciated the description. I had pictured it upside down, with the
support arms drooping down rather than up.

As for the question of wind, everything I've read shows that these hex beams
present a very small wind load.

I have had it up since last October, and we had quite a cold and windy
winter.  This summer we have had a few thunder storms and so far it has
stood up to the test.  I did get the extra ice supports,  When I get the
tower up where it is going to be, it may play differently, but no change in
SWR, and since I can't see anything, I have no idea if anything else is
changed.
