ICOM AH-730 – AUTOMATIC ANTENNA TUNER

ICOM AH-730 – AUTOMATIC ANTENNA TUNER

Fast Tune-up from 1.8 to 50 MHz Band
Remote Control with Icom Transceivers

Descriptions

Wide Frequency Coverage

With a 7 m (23 ft) or longer wire element, all band matching is possible from the 1.8 MHz (160 m) band to the 50 MHz (6 m) band. Efficient for multi-band operation.
* A ground connection is required.

High Speed Tuning

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 minimizes the risk of interference to other stations while matching the antenna.

IPX4 Water Resistant

The tuner case uses a high-strength resin which 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.
