[TowerTalk] Is A Tower Weaker in Some Directions?

[Bill Aycock]

Norm--
Be cautious about your assumptions. The direction of the strongest winds 
does not correlate closely with the direction of the storm path. I one did a 
study for a Rocket test site, (over 30 years ago) that showed (for that 
site) that the strongest sustained wind was almost 90 degrees from the storm 
path. The strongest winds are the result of rotation, not path.
You might consult your local Weather office for help.

Subject: [TowerTalk] Is A Tower Weaker in Some Directions?

Dear Group:

    I just joined Tower Talk -- I've read through the last 5 years of 
archives and have certainly learned a lot I did not know.  What a resource! 
I have a question:

    I have just ordered a US Towers HDX-555 tower. At my QTH, I have the 
option of orienting the base plate in any direction I want to.  My question 
is:  Are these 3-legged towers weaker (or stronger) in some directions than 
others?  (I am not a structural engineer.)  The reason I ask is that most of 
the violent storms that hit here usually come from the same direction.  Will 
orienting the base plate in a certain direction make it any less vulnerable?

Thanks!
Norm
