Alternative Antenna Loading Coil Calculation - Metric

The calculation method is taken from an article by Luiz, CT1EOJ, October 2003 QST.

The method is different from that used in my original calculator.

Frequency: MHz

Length of antenna or arm: Coil position, distance from feedpoint: m.

Wire mm diameter.   Antenna height m.

Loading coil inductance micro Henries

For designing the actual loading coil go here. If you want to use a toroid go here.
