IMPORTANT
READ THIS INSTRUCTION MANUAL
CAREFULLY before attempting to operating the AG-
2400.
SAVE THIS INSTRUCTION MANUAL—This
manual contains important safety and operating instructions for the AG-2400.
PRECAUTIONS
CAUTION! The coaxial cable between this down
converter unit and your transceiver should be clamped
to the antenna pole to prevent the down converter unit
from weighing down the preamplifier.
KEEP the unit away from TV or radio antennas to
prevent interference.

FEATURES
❍ Down Converter for satellite (AO-40) in
S-mode operation
❍ Built-in Low Noise Amplifier (LNA)
Total NF value is less than 1.5 dB,
Conversion Gain is more than 25 dB
❍ Built-in Receiver-Suppression-Control Fil-
ter closes up the uplink and downlink
antennas. (1.8 feet at the minimum)
❍ Built-in the Receiving Protection Circuit
• The built-in circuit protector may not function correctly when the accidental transmission such as
continuous transmission is applied. Such transmission is out of the specified guarantee for accidental
transmission damage to the AG-2400.
❍ Waterproof, weather resistance and pre-
vention from rusting due to salt water.
❍ No power cable wiring is necessary.

CAUTION FOR INSTALLATION
AG-2400 is intended for professional installation only .
We are not responsible for any building breakage, any
damage resulting from a drop of the AG-2400 from a
high place or unstable site resulting in personal injury ,
nor any accident in any other cases. If the AG-2400
must be installed at such high place or unstable site,
be sure to consult an expert engineer.

INSTRUCTION MANUAL
■ Connections
Satellite communications via the AO-40 can be made
when using the IC-910H satellite function mode and
the AG-2400.
For satellite communications, an antenna rotator which
adjusts the antenna direction (azimuth), and an elevation angle rotator which adjusts the angle above the horizon, are necessary .
See back page on how to operate.
ï Converting frequency with the AG-2400
• 2400.225–2400.475 MHz to 144.225–144.475 MHz
• 2401.210–2401.495 MHz to 145.210–145.495 MHz
NOTE: Turn the pre-amplifier controller for 144 MHz
ON during satellite operation with the AG-2400, because the external pre-amplifier control voltage is
used as the AG-2400’s main power.
CAUTION! NEVER transmit on the 144 MHz band.
The AG-2400 may be damaged. The built-in protector may not function correctly when accidental transmission such as continuous transmission is applied.
ï Before setting
Test to operate on the ground before installation is recommended.
q Connect AG-2400 and IC-910H. (See the figure at
left.)
w Turn the IC-910H power ON.
• Push [M/S] to set the 144 MHz as in the MAIN band.
e Push [SSB/CW] to select SSB or CW mode.
r Push [ATT•P.AMP] for 1 sec. to turn the AG-2400
power ON.
• When the AG-2400 functions correctly, the noise level
rise up.
ï Orbit information
Orbit information describes satellite location, wave angles, etc. This information may be available in ham
magazines or organization issues, such as from ARRL
or RSGB handbook, etc.
Use of satellite tracking software is also convenient.
ï AO-40
• Uplink frequency : 435.780–435.495 MHz
• Downlink frequency: 2400.225–2400.475 MHz (S1 BAND)
• Downlink frequency: 2401.210–2401.495 MHz (S2 BAND)
• Beacon frequency : 2400.338 MHz (S1 BAND)
2401.323 MHz (S2 BAND)
Confirm a satellite’s operating mode in advance
through documentation (magazines, etc.) or via appropriate satellite tracking software. In the wrong
mode, you cannot use the satellite even if you receive its beacon signal.

• Use the U-bolts
• Use the nuts • About waterproofing
The AG-2400 can also be installed with self-tapping
screws.
Tighten the U-bolts, Wing nuts, etc. about 2 weeks
after initial installation.
NOTE: Cover the type-N connector with self valcanizing tape to avoid water seeping into the unit. Binding the type-N connector with self valcanizing tape
increases the waterproofing of the connection mold.
