What customers say
The Icom AH-705 is highly regarded by amateur radio operators as an essential, specialized companion for the IC-705. Users consistently praise its exceptional portability and rugged, weather-resistant construction, making it perfect for field operations like POTA and SOTA. The tuner excels at quickly matching various random wire and dipole antennas across HF and 6 meters, achieving low SWR rapidly to maximize the transceiver's limited power. Seamless integration and automatic tuning simplify field deployment significantly. While performance and build quality are excellent, the premium price point is the main drawback for some. Overall, for dedicated portable QRP users committed to the IC-705, the AH-705 is considered the definitive, reliable tuning solution.
Know before you buy
The AH-705 is specifically engineered for seamless integration with the Icom IC-705. While it functions as an automatic tuner, its control features and interface are optimized for the IC-705 ecosystem.
The tuner is designed for wire antennas. For the full 1.8–54 MHz range, you will need a wire antenna at least 30 meters long; for 3.5–54 MHz coverage, a minimum length of 7 meters is required.
No, the AH-705 is strictly for low-power operations. It has a maximum input power rating of 10 watts, making it ideal for QRP (low power) amateur radio setups.
You have two options: it can be powered by two internal AA batteries for maximum portability, or via an external 13.8V DC power source if you are operating from a base station or vehicle.
Yes, the AH-705 features an IP54 rating, which provides reliable protection against dust and water splashes. It is built to withstand the elements during field operations and portable setups.
The unit comes with the necessary cables and a mounting bracket to simplify your setup. You will only need to provide your own wire antenna and the required batteries or external power source.
