■
Power source
DC power cables
Ferrite EMI filter
The transceiver requires a regulated DC power
source of 26.4 V and at least 30 A.
Connect a transceiver directly to a 24 V battery in
your ship using the supplied DC power cable.

WARNING! NEVER
reverse the polarity when
connecting the transceiver to a DC power source.
This will damage the transceiver.
CAUTION:
BE SURE
to use a 24 V battery.

Antenna
Most stations operate with a whip or long wire
antenna. However, those antennas cannot be
connected directly to the transceiver since their
impedance will not match the transceiver's impedance.
Use the AT-141 to connect antennas.
For details about antenna connections and installation,
see the supplied AT-141 Instruction manual.

DANGER! HIGH VOLTAGE!
NEVER
touch the antenna element or wire while
tuning or transmitting.
