The 3 pages that link to Antenna tuner, each with the reason it gives.

• Impedance matchingBroader topic: It presents a more suitable load to the transmitter despite antenna mismatch.

• Maximum power transfer theoremRelated: It applies matching techniques when an antenna’s impedance differs from the transmitter’s output impedance.

• Variable capacitorRelated: Adjustable capacitance can help match an antenna system to a transmitter.
