[TowerTalk] Luso Tower/wind load rating

["Art Trampler" <atrampler@att.net>]

OK, am I missing something here?  If I am understanding how Luso states the 
wind load ratings on its “smaller” towers, they are rated at 

 

 

53.8 sq.ft.　(Maximum wind speed: 25 m/seconds at full extension) 53.8 square 
feet at only 56.25 MPH wind.

 

25 * 3.3 (approximate feet in a meter) * 3600 / 5280 = 56.25 MPH.

 

So, in rough terms, rating at 80 mph is about 40% greater wind speed, so the 
rating at 80 mph would be about 20 square feet (.6 * .6 * 53.8)?

 

That seems awfully low…what am I missing?
