A standard variable-frequency sine-wave oscillator is tuned around the resonant frequency of about 20 kHz while the voltages across the source, the resistor, the capacitor, and the inductor are viewed simultaneously on a four-trace (or two dual-trace) scope(s). ... In both cases the phases of voltages across the circuit elements can be observed ...

The elements Vth and Rth together represent the function generator. However, if the operating frequency is below resonance, the magnitude of the capacitor’s impedance will be greater than that of the inductor, yielding a net negative imaginary part. ... Find the resonant frequency for your particular LC combination, and record it. ...

Sweep the frequency of the MFJ-259 and look for the frequency where the SWR is lowest. In general, this SWR will not be 1:1, but more like 3:1 or 4:1. This frequency is the resonant frequency of the element. You then cut or add wire to the horizontal portion of the wire element until the resonant frequency matches the design value.
