I solved a similar problem on my 130 ft Rohn 35 tower with
the following steps:
1 - cut a triangular plate (1/4 in thick) slightly larger than the
tower such that the tips protrude outside the tower legs
when set inside. Then cut a round hole for the mast.
This can serve as an intermediate mast support above
the rotor. The plate can be installed one or two steps
below the guy attachment, depending on how long you
want the arms to be.
2 - cut some angle aluminum arms (I used 3/8 inch thick
angle aluminum). Attach the angle aluminum to the
triangular plate with two large bolts (3/8 in. or more)
AND attach the angle aluminum to the tower legs with
appropriate sized U-bolts.
3 - attach the guy wire to the angle aluminum arms with
an appropriate sized cable clamp. I marked my arms
in place, then brought them to the ground for the
necessary hole drilling.
Hope this works for you,
de Tom N4KG
