What is an automatic antenna tuner?
The purpose of an automatic antenna tuner (auto-tuner) is to transform (match) a complex load impedance to 50Ω resistive, and to maintain the matched condition automatically as the operating frequency and load impedance vary.
Do antenna tuners reduce power?
Antenna tuners are used almost universally with solid-state transmitters. Without an ATU, in addition to reducing the power radiated by the antenna, the reflected current can overheat transformer cores and cause signal distortion. In high-power transmitters it may overheat the transmitter’s output amplifier.
