Icom AH-6 HF/50 MHz Automatic Antenna Tuner
The Icom AH-6 is a versatile, high-speed automatic antenna tuner designed for seamless operation across HF and 50 MHz bands. Built with a rugged IP54-rated resin body, this compact unit is engineered for reliable outdoor use, offering protection against dust, water, and salt damage. Whether you are setting up a permanent station or heading into the field for portable operations, the AH-6 provides the flexibility to match both long wire and 50 ohm antennas with the flip of a switch.
Optimized for Speed and Efficiency
Experience rapid tuning with a fully automatic system that finds a match in just 2-3 seconds. The AH-6 features a 200-channel memory, allowing for near-instantaneous re-tuning on previously used frequencies. To ensure a clean operating environment, the unit automatically reduces RF output to approximately 0.3 W during the tuning process, significantly minimizing interference with other stations.
Compact, Rugged, and Ready for the Field
Weighing only 1.25 kg and featuring a compact form factor, the AH-6 is 50% smaller and lighter than the AH-730, making it an ideal companion for portable setups where space and weight are at a premium. Its innovative design allows for cable connections without opening the cover, facilitating a quick and easy installation process.
