TL; DR: fire got my tower, can’t replace at same height with stock guy
anchor distance.
I had a Rohn 55 tower that was built in 1971 as 150’ high with 4 levels of
guys and anchors 120’ from the base. Some ten years later they put two more
sections on, making it 170’, and added a 5th guy level (and borrowed the
4th level’s spot on the guy anchor plate for it)
A couple weeks ago the anchors got melted in the CZU Lightning complex
fires (the camera on top caught the fire:

before the camera and microwave cables melted)
I want to replace the tower with 170’ (or 180’) of Rohn 65... but due to
property lines, I can’t get more than a couple more feet out past 120’ from
the base(the default for a 150’) Has anyone on the list gone through the
engineering for guys that are closer to the base than the stock design
calls for?
Due to trees, the first 90-100’ of the tower is virtually unusable, so
every foot counts.
