As far as I know, this is the only software (except for the original but cumbersome NEC) capable of modelling the ground influence on antenna feedpoint Impedance as well as on far field diagram AND incorporating the conductor conductivity. Most other programs account for ground influence on far field diagram, but not on feed impedance, conductor losses are omitted. It might be worthwhile to simulate antenna arrangements with EZNEC, using an elevated Radial System. Radials need not have resonant length, but might be "lengthened" by a radial loading coil in addition to the vertical radiator's loading coil. 73 de Gamal
