I use pipe. Each pipe is buried about 5 feet with a few inches of gravel at
the bottom and about 4 yards of concrete. A friend who is also a CE for the
county came by to see the installation just after the concrete was poured.
He laughed when I asked him if he thought I had enough concrete for a 150
foot tower. He said 4 yards of concrete has sufficient weight to hold the
tower even if poured on top of the ground. :-)

Subject: [TowerTalk] elevated anchor guy points
I purchased a house last year as a compromise house that was OK but didn't
have some things (like more land) that I really wanted but I needed to get
into a house for a new job in a new city. I still have not found the
land/house combination, and need to get a tower or two up in the air. Main
problem is that I have a 50 foot gas pipe line running along one edge of the
property. If I put up towers here, it would be best to locate one or two of
the guys along the property line. I have done some preliminary exploration
and the gas pipeline company may give me a few feet of space at the edge of
their easement which would let me sink an anchor point/points. The problem
is they would like to minimize the "permanent" stuff over their easement iin
case they need to get to their pipeline.
What would help would be to elevate the guy points above ground. Five or six
feet would be reasonable and make them happy.
I have previously used back guyed drill stem buried in concrete to anchor
some towers, but was never happy with it. Towers always stayed up but I just
would have liked the additional security. My towers are 100 and 120 feet
tall sticks of Rohn 45 and I will run some big antennas on them (two or
three monobanders on each of them).
Does anyone have suggestions on what and how to do elevated guy anchor
points which will hold the load of the tower? Has anyone had an engineer do
the calculations for a steel I-Beam buried in concrete or steel pipe? I
can't use a back guy, so the anchor has to take the whole weight of the
tower and stay where it belongs. Can anyone tell me about their experience,
or how to calculate the loads to figure the minimum specs needed or is my
only answer to spend some money on an engineer?
Thanks
