I stand corrected!

I should have calculated it.

Sorry for including gross misinformation about MF & HF skin depth in
typical soil.

A modest radial system will whip a deep ground rod, though. I'm about
10% tempted to break out J.D. Jackson' Classical Electrodynamics and
try to calculate the RF resistance vs. depth of a ground rod, but I
know it's going to be hard to deadly.

Quantitative is always best in this sort of discussion, for sure.

Thanks for the response.
