[Antennas] Wind Damage Statistics-FYI

[Lofstead, Jerry]

Here in the Atlanta, Georgia area, we get "Micro Bursts".  These are
tornado type winds with much strength and only affect an area possibly
measured in 100's of square meters in area.  But, they do a lot of
damage when they hit.  I had one take down a 50' tall tree about 14" in
diameter and left it in relatively small pieces.  It left my HF6V
vertical unscathed!  Generally, we rarely see winds above 50 MPH, except
when the tornado season hits 8-).

Just call you local television station and ask for the weather
department, 
or your local commercial or public airport, and they will tell you the 
stats for your area.  At least they do here in the Fort Worth, TX area. 

There are lots of sites on the web with wind data for the entire 
world.  Just do a search or look at www.noaa.gov for starters. 

The difference between a rare occurrence and a typical storm wind is not

that much, so go for the extreme high wind.  Here in North Central Texas
we 
get lots of wind and the farther west you go the more wind you get.  Ice

and wind go together here all the time because of our proximity to the
Gulf 
of Mexico.  A cold front will be topped out by a southerly wind which
pumps 
lots of warm moisture into the air above the cold layer next to the
ground, 
which then condenses out and causes superchilled water to accumulate and

freeze when it hits the ground, or anything else, resulting in a ice 
storm.  Happens about twice a year here.
