This is the way it's done with the large grain elevators. I was servicing
antennas on one today guyed this way. this was a 150' structure with
multiple heads on it, and it's quite stable, much nicer to work on then a
tower. Has 2 large 8'x6' work platforms on it which are very easy to attach
antennas to.
They use like 6 inch H beams set in concrete with back guying of the post too.
most are set back at a slight angle too in the direction of the tower.
One other interesting thing i should point out is these eleators are made out
sheet steel thats been formed and then galvinized. The stuff does not look
all that strong, but I dulled a drill bit after 8 holes in it.
