Topband: ground radials & conductivity

[k1fz at myfairpoint.net]

    Bill,
 The Back Stay rod was to show with correct galvanization of the 
 1920's  they stood up well. 
 The  parentheses was a reference to wire  used in  antennas. I should  have added "used in antennas". 
 Reading down a little further:
 The ground wire information was to show that  enameled copper wire 
 stood up well in the ground as radials.

 Galvanized can be a problem in some soils. This is the reason that 
 galvanized ground rods are no longer recommended in most applications

 his book).

 would apply to galvanized steel and copper radial wires. I'd be careful 
 using galvanized wire for radials without at first testing it to make 
 sure it would last. It would be a shame to invest time and effort in a 
 radial system just to see it rot away in a few years!
