[johnw7knt@marsweb.com (John Vugteveen)]

Looking for any information, specifications, base measurements, or original 
windload specs. from anyone who may have had one.  I understand that this is 
the early version of the 89' US Towers, but this is not self supporting. US 
Towers has not been much help.  It is guyed at the top of the bottom section 
only.  Any information would be helpful. Thanks.
