Antenna Modeling Software for the MAC
I like using MAC computers because of the inherent stability of the underlying UNIX operating system, and the immunity to most viruses. One disadvantage, however, is that not all types of programs are written for the MAC. I occasionally have need for an antenna modeling program. On my windows PC, I used EZNEC (http://www.eznec.com) which costs about $100.
Antenna modeling, especially in Amateur Radio. Widely used as the basis for many GUI-based programs on many platforms (including popular distributions such as 4nec2 and EZnec on Windows, xnec2c on Linux, and cocoaNEC for Mac OS X). Version 2 is open source, but Versions 3 and 4 are commercially licensed. Momentum: commercial Yes Yes Partial. NEC based antenna modeler and optimizer. By Arie Voors 4nec2 is a completely free Nec2, Nec4 and windows based tool for creating, viewing, optimizing and checking 2D and 3D style antenna geometry structures and generate, display and/or compare near/far-field radiation patterns for both the starting and experienced antenna modeler. 4nec2 is a completely free Nec2, Nec4 and windows based tool for creating, viewing, optimizing and checking 2D and 3D style antenna geometry structures and generate, display and/or compare near/far-field radiation patterns for both the starting and experienced antenna modeler. When running frequency sweeps, linear or logarithmic style SWR, Gain, F/B-ratio and impedance line. MacTNC works only user Mac OS X because it relies on Unix components of the current operating system. Mac Antenna Master Dipole, Yagi, Vertical, Cubic quad, Log periodic, J-pole, coil, and transmission line design package for the Macintosh Macintosh SSTV Shareware SSTV software is now available for the Macintosh computers, for the first time.
I have always wished to have a similar program for the MAC. I have now found an even better program than EZNEC, that is written specifically for the MAC. The program is “cocoaNEC” (http://www.w7ay.net/site/Applications/cocoaNEC/) written by Kok Chen a retired Apple software engineer. The program will run on OS X 10.6 or later, I have been running mine on the latest MAC operating system OS X 10.10, Yosemite, with no problems. This elegant and fast running program is written in OS X’s native programming language. This program takes advantage of all the cores of a modern Intel processor, therefore, it runs fast. The best part, however, is that the program is free.
The downloaded program includes a reference manual and tutorial. Example antenna files can also be downloaded from Kok’s webpage. “cocoaNEC” uses the NEC-2 computational engine. NEC (Numerical Electromagnics Code) was developed by Lawrence Livermore Laboratories in 1981 to simulate the electromagnetic response of antennas and other metal structures.
The antenna characteristics can be input in either one of two ways, via a tabular spreadsheet interface or a special NC programing language interface. The spreadsheet approach is simpler, however, the NC programing interface is more powerful. The antenna’s input information consists of its geometry (for a conductor, the x, y, z coordinates of its endpoints), its excitation, and type of ground (if any).
The summary output for a three-element Yagi antenna located 10-meters above the ground is shown below.
The different color lines represent different frequencies. The antenna can be modeled in free space or above a conducting ground, and the ground conductivity can be varied.
Other outputs consist of a 3-dimensional radiation pattern, driving point impedance and VSWR, as well as a physical plot of the antenna’s geometrical structure. Currents in the various conductors making up the antenna elements can also be plotted, as well as a complete tabulation of the NEC engine output.
If you are a MAC user and have the need to do some antenna modeling, give cocoaNEC a try, I think that you will like it.

Antenna Modeling Software For Linux

MMANA-GAL is an antenna-analyzing tool based on the moment method, which was introduced in MININEC. The program provides ability for changing the language of signs and messages of the program. In addition to English (default), Russian (more information about Russian MMANA available on DL2KQ's website: http:www.dl2kq.de ) and Bulgarian, five more languages have been added with the new release. You now have the additional choice of German (by Alex Schewelew, DL1PBD and Ulrich Weiss, DJ2YA), [more information about German MMANA-GAL available on website: http://dl2kqde/mmana/4-7.htm ], Japanese (by Nobuyuki Oba, JA7UDE), Spanish (by Valentin Alonso Gracia, EA4GG & Dimitri Aguero, F4DYT), Serbian (by Slobodan Ilic' YU1GV), and Czech (by Martin Kratoska, OK1RR) user languages.
Users can easily write a file in their own language by editing the English one. This means, MMANA will be able to communicate with an user in ANY language, actually in the language of his operation system, and that users will be able to write language files themselves. Besides, a user is now able to edit the program's signs, messages and Help file in his own language.
