Not really sure why this was forwarded, but lets look at this
from a common sense point of view.  He wants to put up a C3 or a
C4 for his HF work and a 2M beam.  Mast Rotor and coax on a Hazer
which is on a Rohn 25G tower.  If he uses common sense in guying
and purchases the proper model Hazer I don't see a problem.

What do I have to compare that too.  I am using 59' of Rohn 25G
set 3 feet into concrete.  A H4 Hazer with a 12' heavy 2" mast
and a Tailtwister rotor.  I have a 2m vertical on top about 7' in
height, a CC 40m dipole just under that, and just above the
thrust bearing a Telrex TB6EM tribander.  The Telrex is 85 lbs
itself.  With coax and messenger line and control cables I am
near the max payload of the Hazer.  The tower is guyed twice with
EHS cable.  I have a third set on the Hazer of Phillystrand to
reduce the twisting motion.  I may be pushing the capabilities of
the tower but with what he wants to put up, not a problem.  You
will find no recommendation from Rohn on the use of a Hazer.  If
you are in the same room with a Rep. from Rohn they will refuse
comment on anything put on any of their towers.  The standard
reply is usually get a PE.  But if Marconi had waited on a PE, we
might not be here today.
