[TowerTalk] New N6LF Ground Probe Designs

[Brian Beezley]

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.
