[TowerTalk] Rohn raised guy mounts

[Fred Keen]

We installed raised guy posts similar to Eds. I bought 8" wide flange beams (I beams) 12' long and had 3/4" rods 36" long welded to the front and rear (three each side) of the flat faces of the beams about 8" apart on the lower 3 feet of the beam. We then set the bottom 4' of the beam into a 4' x 4' x 4' hole and and filled with concrete.
This allows me to mow with approximately 8' height clearance around the base.
The tower is 70' Rohn 45, with guy connections at 33' and 66'. The top 20' of the guys are phillystran.It supports a Force 6BA 40-10meter yagi, 80 meter rotatable dipole and 6meter yagi. 
Note, you should take into account the guy spacing as shown in the book going to the ground will be different for the top and middle guys. I would use the dimensions for the top guys. This you can do with a scaled graph chart.

Good luck with your venture.

 The ones I have seen were home made.  12 or so ft of building construction
grade steel I beam with a few guy attach holes drilled near the top of one
end and a couple of holes for some steel rods to be passed through on the
bottom end.  The lower 4 ft or so is buried in concrete with the steel rods
going through at right angles to the I beam.
