Anybody out there using EZNEC?
What is the format of antenna text files that are created by EZNEC?
Can you provide an example or two of EZNEC antenna pattern text files?
The data usually contains columns of theta, phi, and gain.
Thanks.

Hi, I use EZNEC. What exactly are you asking for? Do you mean the text files generated by analysis of the antenna or are you talking about the files for describing the actual wires like NEC uses?

If you want to learn to play with EZNEC, download the free version to play with, go to >Help >>Contents then choose >>Test Drive.

Here are 2 of the pattern plots for a simple dipole in free space:

and the azimuth plot:

It's a nice tutorial that gives a great intro to using the software. You can also check out Terry Dettman's site here: http://www.wx7s.com/training/

73, and let me know if you have any other more specific questions.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer.
