Free Antenna Modeling Software

Dan, AC6LA, has a new domain name, On the site, there is a variety of software, including some programs that are free:

  • MultiNEC – Run Antenna Modeling Programs on AutoPilot – $39
  • EZPlots – Plot EZNEC Frequency Sweep Data – $19
  • XLZIZL – Picture the Rest of Your Antenna System – Free
  • MakeGIF – Make a GIF / JPEG / PNG File from a Clipboard Copy – Free
  • TLDetails – Transmission Line Program with Animated Charts – Free
  • MoxGen – Moxon Rectangle Generator – Free

TLDetails and MoxGen are self-contained, the others require that you
have Excel 97 or later already installed.

TLDetails looks really interesting to me.

    We released FREE version of Antenna simulation software. Is it possible to place a link on your site?

    Best regards,



    DESCRIPTION: EMCoS Antenna VLab Student Version edition contains the full-functional MoM based 3D EM solver. It lets to solve task that fits into as big as 2GB memory for incore or out-of-core calculations. Both, 32Bit and 64Bit versions are available.

  2. I use 4NEC2 ( It isn’t the most intuitive (sometimes) and it has a steeper learning curve than EasyNEC.

    In the past, I used CocoaNEC, also free, but OS X only. Truthfully, I like CocoaNEC better than 4NEC2, but I’ve switched back from Mac to Windows.
