It dawned on me last night as I was mowing the lawn that I could probably
go with the guying dimensions for 110' tower since that is what I would have in
effect. The top guy could be moved down from 101' to 99' or so. The only
problem is that I do not have the room to go out 88' from the tower for guy
anchors. This may not be a problem since I wanted to elevate the guy point to
keep someone from hanging themself in my backyard.
On my 75' Rohn 25G I have one of the points elevated using a steel pipe,
filled with concrete, with an OD of 3 1/2" and wall thickness of 1/4". It
works fine for this appliation.
Are there others who have done this and would care to share their
experiences? This would seem to be an acceptable subsutitution for the
traditional guy point provided the pipe & concrete base is capable of handling
the reactive loads as provided in Rohn's catalog. Using a bit of trigonometry
(remember that fun stuff), the location of the pipe and height can be obtained
so that the guy lines are at the same angles and the load is distributed
properly.
