[TowerTalk] Rohn 25G tower permitting

[Wilson]

I think you are being led around by the short hairs.
How did you decide a 27’ tower needed to be in 3’ of concrete?
For practical purposes there is no bending and no horizontal load at the base of this tower, assuming it is guyed, of course, which –25 must be.
You could stand 30’ of 25 on a piece of 3/4” plywood and three broomsticks and have a fine installation!
The guywire and anchors are your real design hotspots, so a reasonable estimate of overturning moment is necessary.  
With it, you figure the worst guyline load and that gives you an anchor capacity requirement.
You may have the perfect place for some screw in anchors, or an ideal place to display some heavy yard art!
Yes, you’ll have a little horizontal load due to drag on the tower itself, if it’s in the clear, so maybe use rebar or pipe instead of the broomsticks.
I have a 2’ square pad and a tilt plate for mine (40’) and it’s overkill.  The tilt plate is great for antenna maintenance.

And are you required to tell them all about the antennae to be installed?
The less you tell them, the better, since you’ll be changing eventually anyway.
