Turns out that very subject was being kicked around on a recent qrz.com thread: https://forums.qrz.com/index.php?threads/indirect-measurement-of-ground-constants-with-a-dipole.696955/ Dan, AC6LA ____

I apologize. My previous post was meant to go to the Topband reflector, not to Towertalk. Dan, AC6LA _______________________________________________ _______________________________________________ To

This was pretty well studied by George Hagn at SRI in the 60s/70s in the context of antennas for field use of HF and VHF in Vietnam and there are some publications out there. In fact, that's what led

For ham radio purposes, why not measure the effect of ground conductivity instead of the ground conductivity itself?  As Jim Lux says, the conductivity isn't going to be uniform and since you can't m
