EZNEC Antenna Software by W7EL
EZNEC IS NO LONGER FOR SALE. IT IS FREE (see below)
EZNEC PRO/4 IS NO LONGER AVAILABLE (see below)
THERE WILL BE NO SUPPORT OR REFUNDS
The introduction of EZNEC Pro/2+ v. 7.0 has been unavoidably delayed. The
estimated time of introduction is Jan. 14, 2022, but I'll do my very best to
have it ready before then. It is now undergoing extensive testing and updating
of the manual.
EZNEC Pro/2+ v. 7.0 will have all the features of EZNEC Pro/2 v. 6.0, plus
extra features including wire loss for individual wires and the ability to run
external NEC-4.2 and NEC-5 programs for calculation.
Until EZNEC Pro/2+ v. 7.0 is available, you can download EZNEC Pro/2 v. 6.0 by

EZNEC Pro/4+
Use of EZNEC Pro/4 and EZNEC Pro/4+ require a license from Lawrence Livermore
National Laboratory (LLNL) because of their incorporation of NEC-4.2 code for
which LLNL retains the rights. Sale of EZNEC Pro/4 has required the purchaser
to obtain a license before purchasing, and its use requires that a license be
in force. As I will no longer be verifying the existence of a license, I can no
longer distribute EZNEC Pro/4 except as upgrades to those whose licenses have
previously been verified. EZNEC Pro/4+ will be made available at no charge to
as many current users of EZNEC Pro/4 as possible, at the time EZNEC Pro/2+
becomes available. The procedure to obtain it will be detailed on this page.
NEC-4.2 calculations will be able to be done with EZNEC Pro/2+ v. 7.0 by
purchasing an NEC-4.2 license from LLNL and running the supplied NEC-4.2
program with EZNEC Pro/2+ v. 7.0. The speed will be less than EZNEC Pro/4+ and
some features are not available, but results will be very nearly identical.
Both EZNEC Pro/2+ and EZNEC Pro/4+ will be able to do calculations with NEC-5,
also available from LLNL. Not only is NEC-5 priced substantially lower than
NEC-4.2 but it also has a number of advantages over NEC-4.2.
I want to thank the many people who have sent encouraging and complimentary
messages about my retirement. I'm very sorry I haven't been able to respond
because my time has been intensely taken up in getting the new EZNEC Pro+
programs ready. I'll attempt to respond individually after the programs have
been released.
Watch this page for the EZNEC Pro/2+ and EZNEC Pro/4+ announcement and other
updates!
