CONNECTIONS AND INSTALLATION
■
Antenna
Most stations operate with a whip or long wire antenna.
However, these antennas cannot be connected directly
to the transceiver because their impedance may not
match the transceiver antenna connector.
For details about antenna connections and
installation, see the supplied AT-141 Instruction
manual.

Power source
The transceiver requires a regulated DC power of
13.6 V and at least 60 A or 26.4 V and at least 30 A,
depending on the transceiver version.
Directly connect to a 12 V or 24 V battery in your
vessel through the supplied DC power cable.
CAUTION:
•
DO NOT
reverse the DC power cable polarity.
This could damage the transceiver.
•
BE SURE
to use a 12 V or 24 V battery,
depending on the transceiver version.
