You will learn in this lesson why resonant cavities are
You will also see how
resonant cavities are constructed and how they operate.
Next, you will
learn how to tune resonant cavities, and how to couple energy into them and
out of them.

you must use a lower value of inductance and capacitance. Resonant circuits
operating at very high frequencies (VHF) consist of only a few loops of wire
for the inductance and very small capacitor.
