Internet Resonance Calculation said to expect 5,491,367.24 Hz. On breadboard circuit the Antenna Analyzer went to lowest SWR and Resistance reading around 5,240,000 Hz. Or 251,367 Hz. difference.
Using a few known capacitor values ( 3300pF, 1000pF, 150pF, and 10pF) and inductor values (330uH, 56uH, 5.6uH, and .47uH) we can calculate an unknown value- if in range of antenna analyzer frequency range.
In simulator, the voltage source is where antenna analyzer lets us change the frequency and check SWR and resistance settings on a meter. When connected and antenna analyzer first turned ON, the SWR and Resistance meters both peg fully to the right. They both stay right until we get to within a few MHz of the resonant circuit frequency and quickly drop to SWR 1:1 as we reach the resonant frequency.
To find unknown capacitance:
1. Measure unknown capacitance in series with the highest value standard inductor.
2. Connect LC circuit to ANTENNA connector on analyzer with a 50 resistor in series.
3. Adjust frequency knob through each band until you get the lowest SWR. If no dip in SWR meter, change to next lower inductor value and repeat frequency sweep. Keep repeating with lower values until you get the low SWR reading.
4. With this resonant frequency. Solve this equation.
C(pF) =1/ (( .00003948 X F (MHz) X F (MHz) X L(uH)) or
1/ ( .00003948 X 5.24 X 5.24 X 5.6) or
164.72 pF
