AT-141 Antenna Tuner

Automatic Antenna Tuner Unit

Weather Resistant
The Icom AT-141 Automatic Antenna Unit 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 AT-141 immediately tunes for a minimum SWR on any frequency in the HF marine band.

HF Operation on any Size Ship
The 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 AT-141 automatically stores the matching conditions for up to 45 frequencies. Retuning a memorized frequency takes approximately 1 second.
