[TowerTalk] Solid Tower Ground Wires

[Mike & Becca Krzystyniak]

Greetings, 

  As I install my new tower, I was dropping some ground rods next to the
base and acquired some #6 solid copper wire to make the connections (or so I
thought).

  When I went to cut the wire I found out that it had a hard core, most
likely steel.  
  I'm not sure this is plated as the outer copper ring is a substantial
portion of the cross section. 
  As I'm not familiar with the applicatio of this type of wire I wonder if
it is acceptable for the grounding connection between the tower and the
ground rod?

  Thoughts or comments please.  

Thank you.
