An Antenna tuning unit (ATU) (and any of the names in the list below) is a device that is inserted between a radio transmitter and its antenna; when properly adjusted (tuned) it improves power transfer by matching the impedance of the radio to the impedance of the antenna, as it appears end of the feed line connected to the antenna tuner, with the other end connecting to the antenna. (Travel through a feed line usually causes impedance at either end of the feed line to be different.)
The following names are all equivalent: Antenna tuner ,matching network, (antenna) impedance matching unit, matchbox, trans match, antenna tuning unit (ATU), antenna coupler, feed line coupler
