Icom AT-130 HF Automatic Antenna Tuner

AT-130 HF Automatic Antenna Tuner
The versatile AT-130 can be used with a variety of vessels, even smaller boats that cannot use a long antenna element. For example, the AT-130 will match 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 is needed. Just push the [TUNE] switch on an Icom HF marine transceiver; the AT-130 adjusts the antenna and the transceiver to the minimum SWR in any frequency on an HF marine band. The AT-130 allows you to transmit with strong RF output power, and is perfect for maritime mobile operations.

Weather resistant
The AT-130 is housed in a durable, completely weather-resistant acrylic case with rubber gaskets. This allows it to be conveniently installed near the antenna element base.

For Icom HF marine transceivers
Icom's sophisticated AT-130 easily matches Icom HF marine transceivers. The AT-130 easily interconnects with an Icom HF marine transceiver. AT-130 installation is simple. No adjustments are necessary. Just connect the control cable and antenna wire and go!

Quick tune-up
Improved tuning performance...the tune-up time is less than 3 seconds in any frequency on an HF marine band. In addition, the AT-130 has 8 convenient memories to store tuning information. Retuning for a memorized frequency takes about 1.5 seconds. This allows you quick trouble-free frequency changes.

Low power tune-up
The AT-130 emits very little output power (just 300 mW) during the tuning process. This reduces the possibility of causing interference to other stations using the frequency.
