Has anyone taken this? Your impressions? Does it specifically cover
any microwave antenna modelling? I assume EZNEC is the software used,
or is it something else?

I only know about an 'offline' ARRL modelling course
(http://www.arrl.org/catalog/?item=8721).
It's based on EZnec, NecWin+ and/or 'pure' Nec2 models. You can also
use 4nec2 to run the models. From my memory: mostly HF, some VHF/UHF
and no microwave.

NEC does not have any specific frequency limit -- see FAQ
www.nittany-scientific.com
"What is the frequency limitation of NEC?

There is no limit on the frequency range although NEC is usually not used
for frequencies above 2 GHz.

NEC is dependent on the structure geometry not the frequency. If the
structure can be modeled following the NEC guidelines then the appropriate
frequency can be used."

If the ARRL "On-line" Antenna course (See Arie's link above) is anything
like Cebik's two books (Available at Nittany Scientific) then I would
strongly recommend it.
