Icom AT-141 HF Automatic Antenna Tuner 1.6-30MHz

Improves frequency reception

Designed for the Icom GM800 GMDSS and Icom M802 SSB Radio, the Icom AT-141 HF Automatic Antenna Tuner automatically by-passes tuning to improve frequency reception completely weather-resistant acrylic case.

Weather resistant
The Icom AT-141 is housed in a durable, completely weather resistant ASA case, with a rubber gasket. The antenna tuner can be conveniently installed near the antenna element.

Matches all bands
The Icom AT-141 matches all frequencies on the HF marine band. For example, the tuner matches a 7 m long-wire antenna across 1.6-30 MHz.

Full automatic tuning
Just push the [TUNE] key on the transceiver, and the Icom AT-141 immediately tunes for a minimum SWR on any frequency in the HF marine band.

HF operation on any size ship
The Icom AT-141 allows HF operation where antenna element length is restricted due to space.

45 memories for shorter tuning time
To decrease the tune-up time, the Icom AT-141 automatically stores the matching conditions for up to 45 frequencies. Retuning a memorized frequency takes approximately 1 second.
