Icom AH-730 Automatic Pole Antenna Tuner
The new antenna tuner provides fast tuning from 1.8 to 50 MHz
Specifications
Wide Frequency Coverage
With a 7 m (23 ft) or longer wire, tuning of all bands from 1.8 MHz (160m) band to 50 MHz (6m) band is possible. Efficient for multi-band operation.
* A ground connection is required.
High-Speed Tuning
Automatic tuning operation can be performed at a high speed of approximately 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 outputs only 0.3 W of RF from the antenna during the tuning operation. The low power minimizes the risk of interference with other stations while tuning the antenna.
IPX4 Water-Resistant
The tuner housing uses high-strength resin that protects the internal parts from damage caused by water, weather, and salt. The tuner is tested for IPX4 water splash protection. Additionally, the coaxial cable and control cable can be easily connected without opening the housing.
