The OptiBeam design gives you the lowest wind load when the element ends
are pointed into the wind. This is not the case for all yagi designs.
You should run the calculations to determine if the boom or elements
provides more wind load. Barring that do what the manufacturer says.
My OptiBeams, OB16-3 and 40 Moxon have survived very high winds here,
including a sustained hurricane a few years ago. I point mine with the
element ends into the winds. My little Force 12 C3E rides winds out
best with the boom end into the wind. Yesterday was a "normal" spring
day here with gusts measured as high as 42 mph. Just a light breeze
today, blowing about 20 mph right now. Not a good place for wimpy
towers or beams. 73 bob de w9ge
