Calculator for Long Wave (LW) Radio Coil

This calculator will find the value of the long wave (LW) radio coil required for building a ferrite rod antenna given the value of the variable capacitor. The default values are for the coverage of the LW frequency range of 148.5 kHz to 283.5 kHz, utilising a 224 pF variable capacitor. The required coil will be a huge amount, hence manufacturers usually use the thinnest wire in order to occupy the least space on the ferrite rod.
