Can anyone send me a copy or lead me to a manual or engineering specs for a
Tristao MA-550, 55 foot tubular tower, pretty much the same as a US towers
MA-550 if not identical. I have heard that there is a ham in calif that has
manuals etc. for many of the older towers but don't know who it is or if it
is true or not. I would appreciate any assistance on this thank you. Mike
