Rudy Severns, N6LF, has updated his writeup on ground parameter measurement with several new probe designs. A ground probe and NanoVNA let you measure the permittivity and conductivity of your local ground for use in antenna analysis software.

Ground characteristics affect all antennas, but especially vertical antennas and antennas with low horizontal conductors. Accurate ground characteristics let you realistically compare horizontal and vertical designs. They let you evaluate ground-system loss and ground-reflection gain.
