WebOct 6, 2024 · This calculator help for you to estimate the number of turns of your home-brew one-layer R.F. inductor or choke on the design stage. The calculator uses Bob Weaver's equation with round wire corrections. The Coil32 for Android and the cross-platform Coil64 makes it possible to calculate the self-capacitance and Q-factor of the … WebCalculator for Short Wave (SW) Radio Coil. This calculator will find the inductance value of the short wave (SW) 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 SW frequency range of 1700 kHz to 30000 kHz, utilising a 224 pF variable capacitor.
