HF Automatic Antenna Tuner
Tune into your HF marine world
The versatile AT-130 can be used with various vessels, including smaller boats unable to accommodate a long antenna element. The AT-130 effectively matches a 7 m (23 feet) long wire antenna across the marine band in the 1.6 - 27.5 MHz range.
Automatic tuning
No manual tuning necessary. Simply press the [TUNE] switch on an Icom HF marine transceiver; the AT-130 will automatically adjust the antenna for optimal SWR on any frequency within the HF marine band, allowing for strong RF output power during maritime mobile operations.
Weather resistant
The AT-130 is encased in a robust, weather-resistant acrylic housing with rubber gaskets, enabling convenient installation near the antenna element base.
For Icom HF marine transceivers
This tuner seamlessly integrates with Icom HF marine transceivers with a straightforward installation. Just connect the control cable and antenna wire—no further adjustments required.
Quick tune-up
Experience improved tuning performance with tune-up times under 3 seconds across the HF marine band, alongside 8 memory slots for storing tuning data—retuning for a memorized frequency takes approximately 1.5 seconds.
Low power tune-up
The AT-130 transmits minimal power (approximately 300 mW) during tuning, reducing potential interference with other stations.
