<That is my concern too with rotating towers however there are many out

##  with a plane jane tubular mast, you just alternate sides of the mast, for each yagi.
##  EACH yagi needs to  be  TORQUE  BALANCED !     Thats  most of folks issues  right there.  
Its  dead simple to tq balance any yagi. 

## Problem with the  rotating tower concept is..... the tower is 3 sided.... so  ALL the yagis, 
end up on  the  same tower face.    The issue starts when all booms  pointed into the wind.  
You still  end up with a  tq  imbalance. 

##  with all booms broadside to the wind, the yagis are then again tq balanced.... which is... the  fix. 

##  Think of a rotating tower as a 100  to  200 ft long drive shaft.
