[TowerTalk] WTB Rohn 25G tower insulator

One possibility...  The Hy-Gain Hy-Tower multi-band vertical comes with 
three insulators that are used to insulate the base of the antenna from 
the rest of the mounting structure which is set in a cubic yard of 
concrete.  These insulators may be ordered separately as parts.

The Hy-tower is 24 ft of steel lattice tower topped by decreasing 
diameters of aluminum tubing going up to about 52 ft above the base.

If you think the insulators are not strong enough then use two or more 
per leg, not just the one.  If you are at all handy in DIY I think you 
could take a look at the manual for this antenna (available as PDF 
download from Hy-Gain), order the parts you need, and successfully 
insulate your tower.

I redesigned their mount from aluminum to steel and used the stock 
insulators with no issues.  Tower base is mounted about 22 ft above 
ground (on top of an all metal barn) and has a 4-way Phillystran guy 
setup at the 24 ft level.  May be seen on my QRZ page.
