EZNEC Antenna Modeling for All of Us

I missed this while it was happening. I was looking to update my old software to model my new antenna configurations and found out about the change.

As Roy W7EL decided to retire, he made public his EZNEC antenna modeling software (compiled form only).

There is also some neat stuff on NEC-5 end, where there is a collaborative update to the latest version (NEC5 X11) thanks to some great ham inputs! https://eznec.com/NEC-5.htm

The AC6LA add-on AutoEZ is something I plan to check out. https://eznec.com/AutoEZ.htm and https://ac6la.com/

AutoEZ is interesting as it an an Add-On to EZNEC which in also in essence an Add-On to NEC.  AutoEZ appears Excel-based, EZNEC is Visual Basic 6 (obsolete version) with some Fortran modules,  and the core NEC compiled Fortran (Intel Visual Fortran with the mkl math libraries).

Below the “–” line I will include some background from either Roy W7EL (website archived copy or QRZ.com) or a QSO Today Podcast interview he did with Eric 4Z1UG.

Well worth checking out all of these programs.

Also a series of dedicated books by ON5AU that should be considered if you are going to put EZNEC to work:
