Topband: Deployable radials for 80/160M

[Carl]

Around here that wire gets pretty well corroded after a few years just in 
the air from acid rain and salt laden fog off the ocean 20-30 miles away.

I wonder what that does to the conductivity?  OTOH my yagi elements from a 
different alloy are still rather shiny after 30-40 years.

THHN for wire antennas seems to hold up the PVC layer 10-15 years then 
becomes fodder for elevated radials.
