Reg,

NEC2 is public domain, so there are no restrictions. NEC4 was developed by
Gerald Burke at the Lawrence Livermore National Laboratory, and requires an
end user license. The cost is $500.00. See
http://www.llnl.gov/IPandC/technolog...titles/nec.php for
info.

Yes, it does support Nec4, but as you already mentioned, you need a
license to use it.
