Product Description
Automatic Antenna Tuner for Icom HF Marine Transceivers
FEATURES
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 the operating frequency.
