Hi Beaupain,

My thinking on this interesting subject leads me to believe that you
should orient your beam perpendicular to the direction the wind is
coming from... in your case either North or South for a westerly wind.
Then, the only surface meeting the wind head-on would be the boom. This
of course assumes you want to minimize the wind loading force on the
beam, rotor and supporting structure. The wind, blowing on the tips of
the elements, would appear to me to exert a minimal force in this

Of course all this assumes [there's that nasty word again] the wind
direction is a constant. Yet, for all reasonable intents... this
orientation method that I use here in stormy weather appears to work
for my Mosely TA-33 and roof mounted tower. The really "big guns" would
probably follow similar thinking.

As for all the European hams on this reflector... I believe they are
away attending a conference in Liechtenstein where an important paper
is being delivered on "Finding True North When Lost in the Alps in a
