Icom AH-6 Compact Remote Automatic Antenna Tuners are a lightweight, weather-resistant automatic tuner designed to provide reliable multiband operation from 1.8 to 54 MHz. Compatible with both long-wire antennas and 50-ohm antennas such as verticals and dipoles, the AH-6 offers exceptional installation flexibility for fixed, portable, and field operations. Its compact design is approximately 50% smaller and lighter than the Icom AH-730, making it an ideal choice where space and weight are important considerations.

With fully automatic tuning activated directly from a connected Icom transceiver, the AH-6 typically achieves a match in just 2 to 3 seconds and stores up to 200 tuning memories for near-instant retuning on previously used frequencies. During the tuning process, RF output is reduced to approximately 0.3 watts, minimizing interference to nearby stations. Built with a rugged IP54-rated enclosure that resists dust, water, and harsh outdoor conditions, the AH-6 is well suited for permanent outdoor installations. It supports input power up to 120 watts and includes a 32.8 ft. OPC-1465 control cable along with mounting hardware for easy installation.

Whether you're building a compact HF station, installing a remote wire antenna, or seeking a versatile tuner for portable operation, the Icom AH-6 delivers fast, dependable automatic antenna matching across multiple amateur bands.

The AH-6 antenna tuner is compatible with IC-7760, IC-7610, IC-7300, IC-7300MK2, IC-7100, and IC-718.

Supplied Accessories:

• Control cable - OPC-1465, 32.8 ft. (10 m)

• Mounting kit (U-bolts and plates)

Key Features

- Seamlessly switch between long wire and 50-ohm antennas with a simple selector switch, eliminating the need for separate antenna tuners.

- Wide frequency coverage from 1.8 MHz (160 meters) through 50 MHz (6 meters).

- High-speed automatic tuning in as little as 2 to 3 seconds, with 200 memory channels for approximately 1-second retuning on previously matched frequencies.

- Compact and lightweight design with the same footprint as the AH-4 and approximately 50% less size and weight than the AH-730.

- Quick and convenient installation with cable connections accessible without opening the enclosure.

- Minimized interference during the tuning process by reducing RF output to approximately 0.3 watts through an internal attenuator.

- Rugged IP54-rated construction provides dust protection and water resistance for reliable outdoor installation.
