Problem: I have a Rohn 25 G  tower that I want to use with a 40 meter yagi. I know that the tower needs some redoing to get it in shape.  I need the groups expertise to guide me through this redesign.


+++The Rohn 25G is at 65 ft, and it was was constructed of new materials three years ago. It is used only as an internet tower in a rural area to get above the tree tops.

+++The base is buried in 3X3x3 concrete. The top section is pointed.  There two levels of small gauge guy wire. There is a 4 in gray plastic conduit runner from the base underground to house.


++++I have a Yaesu G-1000DX A, enough 7/8 heliax to run the 300 feet down to the shack

++++ I want to update this tower so that I can put a 40 meter yagi.

Things I suspect that needs to be done.
Put on a heavy duty flat top section 
Obtain a mast
The 40 meter yagi - used,  but in good condition from a contester.  I have not pickup this yagi to determine the make or model yet, or wind load. (Get it in shape to use)

etc.

***Could I get some help as to the planning, the obtaining of parts, and possess of construction?.

tnx 73
