This will not answer your question but it is amusing. This guy claims
his SS replacement top section for fiberglass antennas gives you 2dB
gain and a lot of other BS. See:
http://cgi.ebay.com/BASE-ANTENNA-UPG...QQcmdZViewItem
“PRINCIPLE EXPLANATION... THIS UNIT IS A STAINLESS STEEL TOP SECTION
THAT SCREWS INTO THE TOP SECTION OF YOUR EXISTING FIBERGLASS BASE
ANTENNA, AND IT IS A PROVEN FACT STEEL ANTENNAS OUT PREFORM FIBERGLASS
IT ALSO HAS A METAL HELIX COIL TO INCREASE RECIEVE .. THIS UNIT HAS A
LOAD IN IT VERSES YOUR TOP SECTION THAT DOESNT HAVE A LOAD THIS
INCREASES TRANSMIT POWER BY DRAWING POWER TO THE TOP LOAD....”
Ooh, don’t question him, he’s a broadcast engineer! Ha!

Been looking for a used 2 mtr ant. - was reading some comments about
Fiber Glass and Lightning - Someone said "Fiber Glass to lightning is

So, is there something to the comment ?
