ICOM AH-705

The Icom AH-705 matches your IC-705 transceiver to a coax fed or wire antenna of more than 7 m/23 ft long (3.5–54 MHz).

Features

Wide Tuning Range
The AH-705 provides reliable matching from 3.5 MHz to 54 MHz when using at least a 7 m (23 ft) antenna.

Automatic Digital Control Tuning
The built-in 8-bit microprocessor chooses the lowest SWR using more than 1,040,000 different LC (coil/capacitor) combinations.

45 Frequency Memories for Fast Tuning
The LC combinations of 45 previously-used frequencies are automatically memorized. Once a frequency is memorized, the AH-705 tunes on that frequency in less than 1 second. Note that the AH-705 does not memorize a frequency which is normally tuned within 2.5 seconds. Memories are retained only when the power is on.

Weatherproof Design
The AH-705’s tightly sealed plastic case allows convenient mounting virtually anywhere. The AH-705 can be mounted outdoors under your antenna. S. images attached.
