I have written a program to compute the dimensions of a Moxon Rectangle antenna given the desired frequency and the wire diameter.
I was inspired to write this program after I saw a screenshot of a program called MoxGen which runs only on Windoze. That program was written by Dan Maguire (AC6LA).
I was unable to find a program that did this computation natively on Linux.
Thus, Fl_MoxGen was born!
Currently, this program runs on Linux.
It was originally developed on Ubuntu 8.04.3 LTS on a 32-bit computer with FLTK 1.1.7.
Current development occurs on Ubuntu 10.04.1 LTS with FLTK 1.1.10.
It should work on other platforms where FLTK is supported.
I would appreciate hearing success stories from people running this on other platforms.
It is Free Software under the terms of the GNU General Public License, version 3 (or later).
All of my computers run Linux, thus I cannot test this program on any other operating system.
Here is a recent screenshot.
The picture of the antenna which is used in this program, as well as the formulas for computing the dimensions of the antenna, are the work of L.B. Cebik W4RNL (SK) and came from his website. The details of the formulas and such can be found in an article entitled “Designing Moxon Rectangles by Equation and by Model”, which is available at the Cebik website.
This new version adds PDF output capability and fixes a few bugs.
See the CHANGES file for more details.
LATEST version is available for download from Sourceforge.
Please note that I am not an antenna modeling expert (far from it!), so please consider the resulting model as a starting point for any further analysis you might wish to perform.
The output from Fl_MoxGen is then sent to xnec2c. Here is what xnec2c produced.
