Ground Probe Calculator

This Windows program calculates ground permittivity and conductivity for antenna models from the impedance of an open wire line probe. It accommodates a probe partially inserted into hard ground, and it can suppress common-mode current. It models the inductance of the wire that connects the rods and extra capacitance due to dielectric between them. Skin depth can reveal the sampling limitation of a surface probe when the ground is inhomogeneous. The program reads Touchstone, RigExpert, VNA4Win, and W5BIG VNA files.

Another program averages measurements made at multiple locations in the vicinity of an antenna.
