FEATURES
Matches all bands
The AT-141 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] key on the transceiver, and the
AT-141 adjusts immediately to the minimum SWR of
any frequency on any HF marine band.
HF operation on any size ship
The AT-141 allows you HF operation where antenna
element length is restricted due to space.
Weather resistant
The AT-141 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 d e c r e a s e t h e t u n e - u p t i m e , t h e AT- 1 4 1
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-141 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-141 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-141.
This function helps improve receiver gain, depending
on the antenna element length used, and operating
frequency.
