Depends on the antenna design and materials as to which direction makes
the most sense.
The consensus on the SteppIR list is into the wind - especially for
models with sweeps.

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.

I have a short tower bracketed to the house adjacent to my shack. See
QRZ page. 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?
