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.
Low-pass L-network (preferred)

High-pass L-network (alternate)
