antennetuners
An antenna tuner, also known as an antenna matching unit (AMU) or antenna coupling unit (ACU), is a device that matches the impedance of an antenna to the impedance of a radio transmitter or receiver. This impedance matching is crucial for efficient power transfer between the transmitter/receiver and the antenna. When the impedances are not matched, a significant portion of the radio frequency (RF) power is reflected back towards the source, leading to reduced transmission range and potential damage to the transmitter.
Antenna tuners typically consist of a network of inductors and capacitors, often adjustable. By changing the
There are several types of antenna tuners. Manual tuners require the operator to physically adjust knobs or
