Tune in your HF marine world
Suitable for many vessels
The versatile
AT-140 can be used with a variety of vessels, even smaller boats that cannot
use a long antenna element. For example, the AT-140 will match a 7 m (23 feet)
long wire antenna across the marine band in the 1.6 - 27.5 MHz range.
Automatic tuning
No manual tuning
is needed. Just push the [TUNE] switch on an Icom HF marine transceiver; the
AT-140 adjusts the antenna and the transceiver to the minimum SWR in any
frequency on an HF marine band. The AT-140 allows you to transmit with strong
RF output power, and is perfect for maritime mobile operations.
Weather resistant
The AT-140 is
housed in a durable, completely weather-resistant acrylic case with rubber
gaskets. This allows it to be conveniently installed near the antenna element
base.
For Icom HF marine transceivers
Icom's
sophisticated AT-140 easily matches Icom HF marine transceivers. The AT-140
easily interconnects with an Icom HF marine transceiver. AT-140 installation
is simple. No adjustments are necessary. Just connect the control cable and
antenna wire and go!
Quick tune-up
Improved tuning
performance...the tune-up time is less than 3 seconds in any frequency on an
HF marine band. In addition, the AT-140 has 45 convenient memories to store
tuning information. Retuning for a memorized frequency takes about 1 second.
This allows you quick trouble-free frequency changes.
Low power tune-up
The AT-140 emits
very little output power (just 300 mW) during the tuning process. This reduces
the possibility of causing interference to other stations using the frequency.
