[TowerTalk] pointing antenna into wind.

[daniel hearn]

You make a good point Bill. Probably a good solution is to mount the antenna
with the boom attached to the mast at its center, not at the balance point.
Then turn the boom at right angles to the wind. I use a 6 el KLM which is
extremely unbalanced with most of the elements on one side of the boom. The
boom is 57 ft long and wind force on the side of the boom actually buckled
it. It now has side trusses. 73, Dan, N5AR

I think it depends on the size of the antenna, and its configuration.
With my bracketed tower and A3S, I find it much better to turn the
antenna with the element ends into the wind. This produces much less
low-frequency noise generated from the tower in high winds.
