I just took the ARRL antenna modeling course and bought EZNEC+ V4.0 to
provide the tools to do the examples. One chapter was devoted to
limitations and common shortcomings of the software. I think the
course is great and I would select the same software if I was doing it
again. I wonder if you are referring to the free demo package?

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 ?
