INSTALLATION AND CONNECTIONS 2
CONNECTING THE AH-3
Coaxial cable
(from the AH-3)
Transceiver
CONNECTING THE AT-180 -
Coaxial cable supplied
with the AT-180
Note:
e Turn the IC-706MKIl's power
OFF when connecting the AT-
180, otherwise, the CPU may
malfunction and the AT-180
may not function properly.
*The OPC-742 is required when
using both the AT-180 and a 2
m linear amplifier.
CONNECTING THE IC-4KL
Transceiver
The AH-3 can be used for the HF bands only,
although the [ANT 1] connector is used for both HF
and 50 MHz operation. Use a coaxial antenna
switch when you operate the 50 MHz band with the
AH-3 connected.

Do not connect [ANT 2] to the
AT-180. When using an HF to 2 m
wide antenna, use a duplexer
between the AT-180 and antenna
since 2 m signals do not pass [ANT 2]
through the AT-180.
