Hi - I am a new subscriber to the list. I just put up a 3 el Steppir with the
40M option. I have had a problem with the boom rotating in the wind - the
elements move out of vertical with a side wind load. This isn't a very large
antenna and I am a little surprised there would be a problem. On the surface
it seems the windload of the 40M looped elements is too much for two u-bolts
on a 1 3/4" boom.
Any idea how much I can torque the two boom u-bolts before I either crimp the
boom or stretch the u-bolts? I lubed the threads as recommended in the manual.
This antenna replaces a Bencher Skyhawk whose boom broke in last winter's ice
storm. The Skyhawk could have used a boom truss, but that is another story.
Thanks for any insight.
