I thought this might be of some passing interest. Today I excavated the
bare copper ground wire that I ran between each tower leg and an 8-foot
copper-plated steel ground rod when my tower was installed in 1995. The
connection between the wire and the ground rod was made with one of those
"acorn-shaped" ground clamps. Since then, this connection has been
undisturbed under a couple of inches of moist West Virginia loam.
I was fully prepared to find severe corrosion, or no wire left at
all. Instead, what I found was completely intact wire, a pristine ground
rod, and an intact connection between the two that was still nice and tight.
What's the point? I don't know, except that, in some conditions, simple,
quick and cheap may be quite adequate.
