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.

Greetings,
I have an option to put up 80m and/or 160m vertical antennas using Rohn
25 tower, possibly building out the 80m into a 4 square.
On 80m, are there any advantages or disadvantages using towers sections
for the full height, or would say ~3 sections topped off with ~30' +/-
tapered aluminum tubing to top it off work better?
The other question I had was are there novel ways to provide an insulated
base with Rohn 25?
Thanks in advance.
