Thank you for choosing the IC-A220/IC-A220E v h f

a i r b a n d t r a n s c e i v e r

with Icom’s state of the art
technology.
Carefully read this installation guide and the trans­ceiver’s instruction manual before installing and op­erating your transceiver.

x IMPORTANT

READ THIS INSTALLATION GUIDE

install the transceiver. This installation guide contains impor­tant safety instructions.

NEVER install the transceiver where normal navigation of

the aircraft may be hindered.

NEVER install an antenna near any aircraft projection, en-

gine, or propeller.
Install a circuit breaker between the aircraft battery and the
transceiver.

CAREFULLY before

Check operation after installation.
Install the transceiver according to the procedures of this in­stallation guide.

The antenna should be spaced at least 40 cm (1.3 feet) from
any position occupied by any person on board the aircraft or
the vehicle.

The following accessories are supplied with the transceiver.

b USING THE MBA-3

When installing the transceiver with card edge connector, use
the optional MBA-3 as described below.

v PRECAUTIONS

NEVER bend the cables sharply or place the cables too near
the aircraft control cables.
DO NOT place the transceiver where hot or cold air blows di­rectly on it.
AVOID placing the transceiver in areas with temperatures be­low –20˚C or above +55˚C (–4˚F to +131˚F).
NEVER connect the transceiver to a power source using re­verse polarity. Reverse polarity will damage the transceiver.
To prevent voltage drops, solder or crimp the cable lug when
connecting the DC power cable to the power supply.

Use a 50 Ω, vertically polarized, VHF air band antenna.

VSWR should be less than 2.5:1.

Mount the antenna on a flat metal surface or install a ground
plane of at least 120 cm

2

(18 in2).

The following items are required for installation but are NOT
supplied with the transceiver.

• VHF antenna for the air communication band

• Various cables

When you install the transceiver in the optional MB-53,

attach the supplied voltage sticker on the MB-53.

• An antenna cable with a BNC connectors (50 Ω)

• Switches to be mounted on the aircraft yoke

• Headphones. (500 Ω)

• Low-impedance carbon or dynamic microphone

• Preamplier for a dynamic microphone

D Attachment

Unscrew the 10 bottom screws, then remove the bottom q
cover from the transceiver.
Unscrew the four rear plate screws. w
Disconnect the I/O cable connectors J3, J4, and coaxial e
J6 , and then remove the rear plate from the transceiver.

Connect the I/O cable connectors and coaxial onto the r
MBA-3 as illustrated below.

Attach the MBA-3 to the transceiver with the five rear plate t
screws.
Replace the removed bottom cover and 10 screws. y

D Power cable wiring

Use two pairs of #18 AWG wire for the power and power
connections.

Rear view

• Circuit breaker

To prevent physical damage, a 10 A circuit breaker MUST be
installed in the DC power line in the aircraft. Install the circuit
breaker in the aircraft breaker panel or instrument panel to
ensure easy access during flight.

• Power Ground

Connect the transceiver power ground to the aircraft ground.

D Yoke-mounted memory and frequency exchange

switches

D Audio line connection

Use #24 AWG wire for the connections.

For the yoke-mounted memory and frequency exchange
switches, use a two-position spring loaded rocker switch or

transceiver

’s PTT line, and connect pin 9 to the other

’s interlock line to prevent both transceivers from

simultaneously transmitting.
However, when two transceivers are installed through a dual
audio panel, the connections are not necessary.

⁄0 MARKING A MOUNTING HOLE

D Notes for making the mounting hole

The transceiver can be mounted securely in the supplied
mounting bracket.
Remember to allow adequate space for installation of cables
and connectors.
When installing two or more transceivers in a stack, the mount­ing bracket should be 1.3 mm

D Mounting bracket dimensions

(0.05″) apart.

The mounting bracket has 0.6 mm

(0.024″) dimples in the

top, bottom, and both sides for proper spacing.
Mark and cut the mounting holes.
To support the mounting bracket, the rear mounting bosses
should be attached to the airframe.
