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.
