Back in the 70s a friend over in Alma (W7FV ... have since lost track of
him) had just left for sea. We had a storm go through and his Heights failed
dumping the big 20 meter monobander right through the roof above the living
room as I recall.

It is my opinion (and only that) that the wall thickness of the tubes used
by Heights in 1972 (when the tower was fabricated) was insufficient for the
stress I placed on the tower sections. I believe that the wall thickness of
the tubing used today is much greater.
