"Webantenna itself can be considered an impedance transformer. The antenna transitions power received from the RF circuitry through the Tx line (matched to an impedance of 50 Ω in most cases) to free space (impedance of 377 Ω). Matching the input impedance of the antenna to 50 Ω is a requisite to ensure that the maximum " - Shunt antenna
