matching with very low impedances (like mobile verticals) may need series matching. And in fact almost all marine and CB fiberglass whip antennas do contain some form of series matching to bring the very low (typically 3-10 ohms) impedance up to the nominal coax impedance of 50 or 75 ohms. What is an impedance matching device? Matching networks are configurations used to match source and load impedances, and impedance matching devices are the components that make up these networks. Finding these component values can be done using computer simulations, manual computations, or with tools such as the Smith chart.

The voltage ratio (like turns ratio in transformers) is equal to the square root of the impedance ratio, so √20≈8.7. This means that the output voltage will be 8.7 times bigger, so it will be equal to 8.7 mV.
