تعريف antenna tuner في الإنجليزية الإنجليزية القاموس.

(Elektrik, Elektronik) An antenna tuner, transmatch, or antenna tuning unit (ATU) matches a transceiver with a fixed impedance (typically 50 ohms for modern transceivers) to a load (feed line and antenna) impedance which is unknown, complex or otherwise does not match. This mismatch is usually caused when using a non-resonant antenna (one that is not the correct electrical length as compared to the wavelength of the signal). An ATU allows the use of one antenna for a broad range of frequencies. A tuned antenna is never as good as a naturally resonant antenna due to additional induced losses on the feed line due to the SWR (multiple reflections), and losses in the ATU itself
