Calculate number of turns needed to produce a coil with given L
Avoid by-guess-and-by-golly use of turns-to-inductance calculators to determine number of turns to yield the inductance you need.
Using the inversion of Wheeler's formula for inductance of single-layer coils, calculates the number of turns required to produce a specified inductance. Specify desired inductance, coil radius, and winding pitch.
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.
