I've tried to model some OWA Yagis using MiniNEC or NEC-2 interfaces, like
Eznec and 4NEC2 (a friend used also AO and YO), but the results are
disappointing, especially regarding the impedance, which is one of the most
important result for OWA.
Even entering real antennas, like the NW3Z 6 elements OWA yagis, the results
are not correct...
For this and other reasons, I'm thinking about buying NEC-4 engine from LLNL
and I would to know if this software is copy protected with some hardware
dongle or software key or not.
I read the licensing documents and it seems that there is no copy protection
supplied, is it true?

If you can't make them work then I would forget about computor
programs.
They obviously are not your cup of tea despite how many people use
them with success. You would be better off finding out what you are
doing wrong than sending money at the problem.
