In my humble opinion, EZNEC is a POS for anything other than a simple "wire
antenna". Try to do a true ground plane with bent radials? Try to do a
simple patch? Try to do a J? Try to do ANY configuration other than a wire
dipole and the sucker chokes.

I've modeled ground planes with bent radials and J antennas
using EZNEC and got reasonable results. Never tried a patch.
EZNEC's limitations are well known and well documented so
knowledgeable users can avoid those pitfalls. Of course,
nothing is foolproof.
