4nec2 freeware now available for Nec-4.
 

Hello...,

Just released the latest new 5.5 version of the 4nec2 freeware antenna
modelling package. Now capable of running both a Nec-2 or a Nec-4
engine.

See http://www.si-list.org/swindex2.html

Note however that in order to run Nec-4 you need a license from LLNL.

73's,
Arie.
