Replacement for Icom IC-AH4
AH-730 Automatic Antenna Tuner
The AH-730 HF Automatic Antenna Tuner can be used with a variety of Icom HF Amateur radios.
Wide Frequency Coverage
With a 7 m (23 ft) or longer wire element, all band matching is possible from 1.8 MHz (160 m) band to 50 MHz (6 m). The AH-730 is highly efficient for multi-band operation.
* A ground connection is required.
The automatic tuning operation can be made at a high speed of about 2 to 3 seconds. It has 45 memories to store the minimum SWR settings. When re-tuning the same frequency, matching can be achieved in about 1 second.
Minimum RF Output for Tuning
The AH-730 emits only 0.3 W of RF output from the antenna during tuning operation. The low power minimises the risk of interference to other stations while matching the antenna.
The tuner case uses a high-strength resin that protects internal parts from water, weather, and salt damage. The tuner is tested to IPX4 water splash protection. In addition, the coaxial cable and control cable can be easily connected without opening the case.
