Nonsense ... I've seen commercial fiberglass antennas last 
for 10+ years.  If I needed to do so I could renew A SteppIR 
(even a four element antenna) for less than $250 (eight ESTs at 
$30 each).  $25 per year of use ... that's a bargain.  I've 
spent more than that repairing aluminum antennas that weren't 
10 years old. 

BTW, you might be surprised what the right coatings can do.
