[Milsurplus] Fiberglass antenna poles

[David Stinson]

Re: Fiberglass antenna poles-
I've used them a lot, but I don't know about 40 feet.
The fiberglass poles won't stack very high 
without reenforcment.
They will split at the end where one pole nests into another.
I use a hose clamp to strengthen the reenforcing ring
on one end of each of the poles and I've gotten 30 feet
without any trouble.  Even with reenforcement, you can
still split them or break-off the tip in the lower pole.
I don't remember how high you can go with reenforcement,
but I think 40 feet unguyed would be pushing it and
I'd worry about breaking-off the insert tip if the wind
got very froggy at 40 feet.

Also- the sun will cause the outside of the poles to develop
fiberglass "hairs" that will sticker you all over and be almost
impossible to get out of your clothes.
To avoid this, get a can of any exterior paint and give the 
poles a coat-  not more itchy stickers.  
All of mine get this treatment.
