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).
