INSTALLATION AND CONNECTIONS
2-4
Connecting an external DC power supply
Confirm that the transceiver is OFF before connecting
the DC power cable.
L
We recommend using Icom’s optional PS-126
(DC 13.8 V/25 A) power supply.
L
When connecting a non-Icom DC power cable, the
transceiver needs:
•DC 13.8 V (Capacity: At least 21 Amps)
• A power supply with an over current protective line and
low voltage fluctuation or ripple.

Connecting the antenna tuner
The AH-4 matches the IC-7300 to
the optional
AH-2b or a long wire antenna more than 7 m/23 ft long
(between 3.5 MHz and 50 MHz).
NOTE
: Before connecting, be sure to turn OFF the
transceiver power.

See the AH-4 instruction manual for installation and
connection details.
