[TowerTalk] Carbon fiber & lightning

[Jim Jarvis]

Got a peripheral question, which relates to the
lightning thread.  Would be interested in the groups
thoughts.

Been considering two sailboats.  One has a traditional guyed
aluminum mast, grounded in a typical fashion...inadequately.
THAT, I can fix.

The other has a freestanding carbon fiber mast.  No way to
ground it.  Conductivity unknown, but I assume somewhat resistive.

Which is safer?  And if I put an antenna (or lightning rod) at the masthead,
does it get worse, or better?
