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.

Does anyone know how I can model a coaxial sleeve antenna
on EZNEC ?
