Features
Wide Frequency Coverage
Provides matching across all bands from 1.8 MHz (160 m) to 50 MHz (6 m)*, enabling efficient multiband operation with a single wire antenna. Ideal for portable and field operations where quick antenna setup is essential.
Wire length requirements: 1.8 MHz band: 30 m (65.6 ft) or more, 3.5 MHz band and above: 7 m (23 ft) or more. A ground connection is required. Tuning may not be possible, depending on the environment and conditions.
SO-239 Antenna Connector for 50 Ω Antenna
The SO-239 antenna connector provides a direct connection to a 50 Ω antenna. Both long wire and 50 Ω antennas, such as verticals and dipoles, can be used* and are selectable with a switch.
Do not connect two antennas at the same time to prevent damage to the antenna tuner during transmission.
Compact & Lightweight Body for Portable Operation
The same compact size as the AH-4, 50%* smaller and lighter than the AH-730. Cables can be connected without opening the cover, enabling quick and easy installation.
Approximately
High Speed Tuning
Simply press the "TUNER" switch on the connected transceiver for fully automatic tuning in 2–3 seconds. The 200-channel memory stores matching settings, enabling re-tuning at the same frequency in approximately one second.
Minimized Interference During Tuning
During tuning, the AH-6 reduces RF output to approximately 0.3 W through the attenuator, minimizing interference with other stations.
IP54 Rugged Construction for Outdoor Installation
The body is made of a high-rigidity resin. With a water-resistant structure that includes waterproofing, weather resistance and protection against salt damage, it can be safely installed in various outdoor locations.
Supplied Accessories
- Control cable OPC-1465 (10 m, 32.8 ft)
- Mounting kit (U-bolts and plates)
