Abstract: An automatic antenna coupler is described which uses a variable inductor and a pair of variable capacitors which are alternately switched into the network; the first while tuning the inductor, and the second after the inductor is tuned. While the inductor is tuned the first capacitor is swept through its range of values so that its capacitance changes at a rate much greater than the change in inductance. A control system responsive to the ratio of forward to reverse line voltage detected by a directional coupler stops the tuning process.
