I think you are making a mistake by not asking for a 40 foot permit. 30
feet is now even a 1/2 wave at 30 feet. Ask for 40 or even 50

You just have to realize you are dealing with a pack of A'Holes and act
They, as usual, know nothing and have no common sense or judgement. We have
let them get in charge of our lives because no one fights them. They can
obstruct anything, and do, but NEVER contribute anything positive of any
A bright eight year old would see that with TWO brackets NO overturning
moment can get to the base, unless the tower pulls the house over of course.
The vertical load of 30' and a tribander could be carried by a piece of wood
on top of the ground! The Rohn base would be great just sitting on dirt.
Show them 18" square by a foot deep and see what they say. Of course your
three pipes in the concrete would be fine too. Truth is, two well installed
brackets would hold that rig up with NO base. I think Rohn even sells a
bracket with vertical diagonals going down, precisely to install a tower on
the side of a building. I've seen them somewhere.
How do you know you need their approval?
Are you in a "town", have neighborhood covenants, or what?
What if you made a nice drawing and submitted it?
If they want to reject it, they should have some grounds
You DO have mfg spec's, at least drawings, on the brackets, in the catalog.
And there is a table of bracket layouts in the catalog, although it may not
go as low as 30'.
You may have trouble because Rohn does not approve ANY self supported height
of 25G. they want support on the top section.
Maybe one of the consultants on this group will sell you a stamped design
reasonably? If your drawing is stamped, the AHs can't reject it without a
lot of grief.
I had a 30' 25G in Houston, with one bracket at about 15', survived several
hurricanes up to about 60 mi/hr. My base was an old cut off section in a
one foot hole with two whole bags of Sakrete. I climbed it many times and
it ws fine. Neat thing was, I could reach the beam from the peak of my
roof, never took it down until I left.
Keep us posted,
