Description
Icom AH-4 Automatic Antenna Tuner
The Icom AH-4 automatic antenna tuner is designed to work with select ICOM transceivers including the Icom 703, 703+, 706 MkIIG, 718, 746, 746Pro, 756, 756Pro, 756ProII, 756ProIII, 7000 and 7200. It provides reliable matching of frequencies from 3.5 to 54 MHz when using a wire of at least 23 feet (7 m) in length. The built-in 8-bit microprocessor chooses the lower SWR condition from more than 1,040,000 different LC (coil/capacitance) combinations. The LC combinations of 45 previously-used frequencies are automatically memorized by the AH-4. Once a frequency is memorized, the AH-4 tunes on that frequency is less than one second. (Memories are retained only when the power is on).
