Suitable for many vessels
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 SSB 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 SSB marine transceivers
ICOM's sophisticated AT-130 easily matches ICOM MF/HF SSB marine transceivers. The AT-130 easily interconnects with an ICOM marine radio 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.

Dimensions: 230(w) x 340(h) x 80(d) mm; 9.1(w) x 13.4(h) x 3.1(d) in (projections not included)
Weight: 2.7 kg; 6.0 lb
Usable temperature range: -30?c ~ +60?c
Rated voltage: 13.6 V DC +/-15% (negative ground) (supplied from an icom hf marine transceiver)
Current drain (at 13.6 V dc): 2 a
Frequency coverage: 1.6~30 mhz (with the antenna length 7 M (23 ft) or longer)
Input impedance: 50 ohms (unbalanced)
Max. Input power: 150 W (pep)
Input power during tuning: 10 W
Auto tuning time: 1.5 sec. (Returning for a memorized frequency), typically 2~3 sec. (When operating band has been changed)
Auto tuning accuracy: vswr 2.0:1
Insertion loss: 0.5 db (with a 50 ohms load, after tuning)
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.
