Matches all bands
The AT-140 matches any frequency on every HF marine band. For example, the tuner matches a 7 m; 23 ft long-wire antenna across 1.6-30 MHz.

Full automatic tuning
Just push the [TUNE] switch on the transceiver, and the AT-140 adjusts immediately to the minimum SWR of any frequency on any HF marine band.

HF operation on any size ship
The AT-140 allows you HF operation where antenna element length is restricted due to space.

Weather resistant
The AT-140 is housed in a durable, completely weather resistant ASA case with a rubber gasket. The antenna tuner can be conveniently installed both on the deck or in the cabin near the antenna element.

Simple installation
Installation is simple. Just connect the control and antenna cables. You never need to open the cover.

45 memories for shorter tuning time
To decrease the tune-up time, the AT-140 automatically stores the matching conditions for up to 45 frequencies. Re-tuning for a memorized frequency takes approx. 1 sec.

Super capacitor for memory backup
Even if the AT-140 is not used for approx. 1 week, the built-in super capacitor backs up contents of the 45 memories.

Low power tune up
The AT-140 emits low output power during tuning. This feature reduces the possibility of causing interference to other stations.

Tuner through function
The tuner through function is built into the AT-140. This function helps improve receiver gain, depending on the antenna element length used, and operating frequency.
