Amateur Electronic Supply (AES) catalogs in the 1980's and 1990's had a lot
of info on heights towers. There were a number of hams around Atlanta that
had the 80 to 100 foot towers. The consensus is that the towers were
somewhat over rated. But only one tower blew down that I remember. Belonged
to WB4ECE/N4YD (SK).
Great pictures of all the towers, specs, packages, even the screw operated
hinged base. I personal saw the towers but not the base.
AES has carried extensive information on other aluminum towers and US Towers
over the years, too.
Sorry my copies are in storage.
