Re: [TowerTalk] Can 1/4" or 3/8" Andrew SUPERFLEX be used for a Rotor loop?

Mac,

Prior posts said don't use FSJ4 outside side the Cu shield is spiral 
rather than solid and water can migrate.  So is it correct that has not 
been a problem for you?
Ecoflex has also been mentioned in the thread. Loss seems to fall 
halfway between AVA5 and FSJ4 @50Mhz.  Is there an Ecoflex distributor 
in the US?  Although UK price looks super high.
