The radio club at Hughes Aircraft in Canoga Park, CA (WD6EZI) had one  
of these towers with a TH6DXX from ~1979-1994. I don't recall the  
weight of the TH6DXX, but it was a bit lighter than the TH7DX, which  
weighs 75 lbs.  It was on top of a building and exposed to occasional  
high winds.  It seemed pretty stable with that load, but after  
several years the tower developed somewhat of a bow due to wind  
loading and would no longer retract.  The installation did not  
survive the 1994 earthquake (nor did the building on which it was  
mounted).
