Moxon Rectangle Calculator
This page calculates the details needed for building a Moxon rectangle antenna as popularized in various places including the October 2011 QST. Rather than clutter this page with commentary I've put it on a different page.
Acknowledgements: Moxon concept G6XN, BASIC generator L.B. Cebik, GUI concept and layout AC6LA. Plentiful implementations: http://moxonantennaproject.com (and builders/contributors). Oh, and KO4BB for the wallpaper.
Unlike AC6LA's version here the input unit select box takes precedence, so don't use a # on wire size. All calculations are done in wavelengths internally, so it's possible to input one unit and get a different one out. Calculations happen whenever the input controls lose focus, but use the Calculate button to read everything fresh and do calculations more reliably. For 300 ohm ideas check this page.
