MoxGen will show you the dimensions and (optionally) generate an antenna model file for a 50 ohm Moxon Rectangle antenna, given the design frequency and wire size. The program is based on an algorithm developed by L. B. Cebik, W4RNL.

For a complete description of this antenna start at LB's Moxon Rectangles page.

For the details of the algorithm see his discussion at Designing Moxon Rectangles by Equation and by Model.
