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.
Icom AT-141 is compatible with:
- Icom GM800 GMDSS MF/HF Marine Transceiver with Class A DSC
- Icom IC-M802 MF/HF Marine Transceiver
