Antennas
Impedance matching calculator
L-network component values to match two resistive impedances. Low-pass and high-pass solutions with Q factor.
Impedance matching calculator
This calculator matches resistive loads only (the R you measure at resonance). If your load is reactive — an antenna off resonance — tune out the reactance first or absorb it into the network by adjusting these starting values on an analyzer.
