[TowerTalk] Antenna on high winds...

[peter.voelpel]

It does not matter whether the boom is round or square, what counts is the
projected surface of the boom depending on its diameter and if it is less
then the surface of the elements or more.
With such short booms and many elements as on the Optibeams I guess it will
be right to turn the side of the boom into the wind

i always point the antenna elements  straight into the wind. The OB beams
use square booms and that takes
a lot more pressure on the mast and rotator than a round boom ? Wright ?

Hello TTers,
For a lot of years (almost 20) I´ve been placing my Explorer 14 straight
into the wind to avoid stress to the yagi and also to tower and rotor. So,
when I had a strong south wind I pointed the antenna to North or South
alternatively. If I remember correctly there was a time when I had no rotor
and the antenna pointed itself to the wind direction with just a slight
breeze (just like a weathervane). I know this thread has been widely debated
here several times but it came up to mind while reading the manual of my new
Optibeam OB11-3W clearly says: ¨At strong winds the antenna should be placed
in a way that the tips of the elements show straight into the wind wich
means that the boom stands broadside to it¨...I know that you should follow
what manufacturers say but I would like to know what´s your opinion about
this (once more). Thanks and 73s!
