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 clicking here:
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.
