I need some advice from the tower gurus. I am planning on erecting a 50 foot
Rohn 25 tower on my city lot in such a way that will require one anchor point
be the house itself. I am looking for advice from someone that has done
something similar and opinions from anyone else.

top guys I will run two wires away from the house to elevated guyposts. The
third guy will run back inline with the peak of the house. I propose attaching

mast that runs vertically down through the roof peak. The mast will sit on an
assembly of wooden 4x4s that are attached to the ceiling joists and rafters.
Suggestions on mast material and diameter? No waterpipe, right? It would

be safe if properly designed and constructed. Your thoughts?
Thanks and 73,
