I am working on a 40M antenna project and want to split the driven element for 
sure and perhaps insulate all the elements from the boom.  

I noticed that W3LPL and others are using Garolite LE.  According to the specs 
I read it has a tensile strength of 14,100 PSI lengthwise and  10,400 PSI 
crosswise.  He mentioned several years ago that he did not use the Garolite for 
40M elements because it was not strong enough.  

Looking at McMaster Carr Garolite Grade 11 is 58,600 PSI lengthwise and 41,900 
PSI crosswise - about 4 times stronger than LE..  It is about twice the price.  
GP03 Electrical Grade Fiberglass is about half the price of Garolite LE and 
seems to be about the same strength.

If anyone has experience or knows the difference in all these materials and 
whether there are significant differences in how well they hold up in the 
environment, I would appreciate knowing.

The other question is whether to insulate all elements or only the driven 
element.  Anyone know the pros and cons?
