Icom AH 4 Mobile Automatic Antenna Tuner for HF & 6 Meters

The AH-4 comes with a 16 foot (5 m) control cable that connects to the rear panel of compatible ICOM transceiver. A 16 foot (5 m) raw coax cable and two PL-259s are supplied to connect the transceivers antenna output to the AH-4 antenna input. The PL-259s must be soldered on by the user.

This tuner may be attached to a pole using the two supplied U Bolts, or to a flat surface

- Designed to work with select ICOM transceivers including the Icom 703, 703+, 706 MkIIG, 746, 746Pro, 756Pro, 756ProII, 756ProIII

- 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. It can also be used for matching 7 to 54 MHz when used with the optional ICOM AH-2b antenna element. 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)
