[amsat-bb] Fiberglass Poles for Antenna Mounting?

Years ago there was a test report on the differences between metal and 
plastic crossbooms. It was shown that there is no measurable difference 
between the two if the antennas are installed with elements 45 degrees from 
the crossboom. Here is one of the discussions from 2002...


I had to drive about 160 miles roundtrip to purchase a  2 inch diameter 12 
foot solid fiberglass  boom that I used to build my Oscar class station in 
1997.  Now I use the metal crossbooms supplied with my antenna's in my two 
sat stations. If it really made a  measurable difference wouldn't Cushcraft 
(AOP-1), and M2( Leo pack) used a non metallic boom?
Anyway there is plenty of talk about this in the archives, and if your going 
to use fiberglass I would go with the solid rod as it will last much longer 
then a tube. I still  have mine stored on the ground in NJ, if anyone want's 
one, it's free.....

Subject: [amsat-bb] Fiberglass Poles for Antenna Mounting?

In reading the descriptions of various directional antenna installations, I 
often see a statement that the last section of mast between the rotator and 
antenna is non-metallic (most often fiberglass, I believe).

What is the best source for a suitable length of fiberglass pole of the 
correct size?

I would not be surprised if the source is outside of the radio world... 
perhaps a round fiberglass pole intended for as a tool handle, for example. 
Just a guess.

Appreciate any suggestions.
