Hello to all,
Hi Gamal,

does anyone of you have experience with EZNEC modelling software?
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.
As far as I know NECx (EZNEC only is a front-end) needs an
add-on for this purposes called SOMNEC calculating Sommerfeld
Parameters, whatever this my be...
Most other programs account for ground influence on far field diagram,
but not on feed impedance, conductor losses are omitted.
One problem for NECx simulating small antennas is that it cannot
compute "pulses" *very* small compared to wavelength. Here
MiniNEC works better since very short segments will be computed
more reliably.
