Antenna Design Software

Programs for Yagis

• Yagi Optimizer (YO7) by Brian Beezley K6STI - highly recommended
• Yagi Analyzer (YA) by Brian Beezley K6STI - YO without the optimizer
• Yagimax
• YGO (Yagi Genetic Optimizer)
• Antfo - BASIC program for K1FO Antenna Designs
• Programs for DL6WU Yagi Designs
  • dl6wu-gw by Ian White G3SEK, available as a BASIC program or as an executable file from http://www.ifwtech.co.uk/g3sek/diy-yagi/.
  • Yagi by John Drew VK5DJ, available as a zip file from http://www.corprit.net/~jdrew/ (click on "Amateur Radio" and then on "Yagi Calculator".
  • Antdl6wu - another BASIC program for DL6WU designs.
  • Spreadsheet by VK3AUU for DL6WU yagis.

NEC (Numerical Electromagnetics Code) and Derivatives

• MININEC
• NEC-2
• NEC-4 - latest version, not available outside the USA
• NY (NEC Yagis) - comes with YO (see above), calibrated to NEC-2
• ELNEC by Roy Lewallen W7EL - early version of EZNEC
• EZNEC by Roy Lewallen W7EL - standard version calibrated to NEC-2, professional version available using NEC-2 or NEC-4 computational engine (to confirmed NEC-4 licensees only).

For a fairly comprehensive comparison between the various commercial realizations of NEC-2 and NEC-4, see:
"Modeling Software, Part 1" by L.B. Cebik W4RNL, QEX, Sep/Oct 2005, p54-59, and
"Modeling Software, Part 2" by L.B. Cebik W4RNL, QEX, Nov/Dec 2005, p50-56.

Further reviews of these and other software programs by experienced users would be welcome.
