Copper-clad rods will greatly outlast galvanized rods.

Reg Edwards, G4FGQ had among his trove of free programs one called
"Earthies", if I recall. Reg is now a silent key (SK) but his programs
survive and are still available free.

Search on: K3HRN site with G4FGQ programs. The site will appear. I had
always wondered what Reg looked like. His portrait is on this site.
