Why do you want to point the antenna into the wind? I do just the
opposite for my OB16-3 ... less stress on the elements.
Depending upon the spacing, you could also be getting some resonance in
the air space between the antennas, but you're probably correct that it
is the one of the antennas. It could also be the tower itself, of of
course.
In any case, once you find the source of the noise you should be able to
use some kind of mechanically lossy dampener to kill it. If you find
the source, somebody here will almost certainly have a suggestion for
what you could use.

C3, 6M3 and 2M7. I have a low frequency noise when the wind blows and I suspect
the C3 is the source. Sounds like an airplane is flying close by. Rotating the
antenna so that it is perpendicular to the wind direction diminishes the volume
somewhat.
It is not a huge deal, but I'd like to keep the antenna pointed into the wind
when it blows. Is there any simple way to eliminate or cut down on the noise?
