[TowerTalk] Rohn 25 Vertical & Guying

[Patrick Greenlee]

Fiberglass sucker rods are solid "pulltruded" fiberglass, strong, and 
insulating. They come in different diameters as you will see when 
Googling.   Google "fiberglass sucker rods".

I have purchased used ones for a nominal $20.  Being 37 1/2 feet long I 
cut them about in half to carry home on my pickup's roof rack.

I have a Hy-Gain Hy-Tower multi-band vertical which is a steel lattice 
tower 24 ft high topped by decreasing diameter aluminum tubing for a 
total height of 52 ft.  It comes with insulators for the legs.  This 
tower/antenna is free standing so the insulators have to do the whole 
job of keeping the tower erect.

These insulators can be purchased separately, I think.  If you need more 
strength use 2-3 or more of these per tower leg.  Heavy wall aluminum 
tubing to fit the insulators was included with the tower/antenna but I 
replaced it with solid steel rod because I customized the mount and 
needed to weld the parts.  Unable to weld aluminum to steel I replaced 
the aluminum parts with steel. These aluminum tubes are available as 
well. They were intended to be set into the concrete foundation but I 
roof mounted mine on a steel building, no concrete, no radials, building 
as counterpoise and worked well so far (3+ years.)

Some folks have used UHMW plastic and made their own insulators. What 
suits you is based on your DIY abilities vs your pocketbook.
