Hello
I know a number of locals who have crank up towers and they have them 
partially cranked up.  For example a 70 foot Hy-Gain cranked to 50 feet. 
 Doing this they leave them set at this level all the time, regardless of 
weather conditions.  Is there a way to determine the gain in square footage 
of wind load at heights lower than the rated wind load at full height? 
 Thinking along these same lines if a crank up is rated at 16 square feet 
at 60 MPH, then if I have 7 square feet on the tower what is the wind speed 
it should be able to handle (e.g. 70 MPH?)?
