[TowerTalk] Winds

[john at kk9a.com]

I got used to working on strong winds while owning a station in Aruba.
There were very few calm days during the winter months. Rope ends would
often wind up in someone else's yard if not tied at the ground and it was
challenging to single-handedly bolt antennas to the mast. I am sure that
my tower paint found its way on to the neighbor's house and pool.

My place out in KH6 is an example of how much stronger the wind is up top.

I live on a very steep slope facing the tradewinds, which normally blow at an
average of 12-15 MPH.  When it is blowing this hard it is impossible to raise
or lower antennas.  So any raising or lowering must be done at lower speed
levels.

Why, when the wind is only 5-6 MPH it is usually closer to 15 MPH at the
top of
a 90 foot tower.  It is amazing how at the base you feel almost no wind
but it
quickly picks up once you get about 20 feet or so.  I've had many 200 ft
towers
on the mainland but have never experienced such a big difference in
surface and
top of the tower speeds.

Being on a steep upslope is the reason, I'm sure.
