[TowerTalk] Boom Material

[Wes]

It depends.  Electrically you will be fine unless you're using a published 
design that used through-the-boom elements, in which case there might need to be 
adjustments.

Physically it will depend on many things.  Wall thickness of course will affect 
stiffness.  Another major concern is UV degradation.  I would not hesitate to 
recommend Strongwell EXTREN.  I bought two 20 foot lengths of 2" x 2" 1/8" wall 
tubing for an LPD project that I never finished.  The stuff has been laying on 
the AZ desert dirt for 20 years and it's in perfect condition.  Other fiberglass 
has disintegrated in a couple of years.
