I plan to install a 90 ft. vertical Rohn 25 that is fed with two 'L'
networks for 160 and 80 meters.
This is described in Low-Band DXing by John Devoldere ON4UN.
I think I can do everything necessary except I have not been able to
find insulators for the base of the tower. There was one commercial source
but they wanted $300.00.
This is a 'budget' project. The towers were acquired by taking down
"TV" towers that were no longer in use. The Coax is commercial hardline
purchased for $30.00 (260 ft!)
The only 'plan' that I have is to build 6 metal disc welded to rods that
fit inside the tower legs. They would be insulated with Lexan and bolted
together in such a way that the bolts would also be insulated. I have some
1/2 inch lexan - from a flee market.
I am aware that Rohn made insulators for the tower legs but they are no
longer available.
Ideas and opinions are needed and welcome.
