The Moxon-Beam by DK7ZB

The lengths for the Wire-Moxon, only for non-insulated 1-mm-wires!
S is the complete length of the radiator wire, R for the reflector, F for the spreader (center to corner).

Design Considerations

This is a discussion of fitting a poynomial formular to the data using regression analysis. The raw data is not supplied but is given in graphical format. There is no discussion on how this data was measured. The formulars are given in a BASIC program. This program appears to be copied by several web calculator, however, you cannot be certain as most of these sites fail to supply the sorurce.

Linux Calculator


Fl_MoxGen is a program which will compute the dimensions of a Moxon Rectangle antenna when given the desired frequency and diameter of the construction material (typically wire). It also generates PDF and xnec2c outputs.
