EQUIPMENT INSTAllATION
5.1 INDIVIDUAL EQUIPMENT INSTAllATION
After cable check-out. the aircraft is ready for the installation of the MagnaStar C-2000
equipment. The following check-out must be followed prior to application of aircraft power.
ANTENNA
a) The Antenna should be mounted to a paint free metal grounded surface. Ensure that
the screw contact (countersink) surface of the Antenna is free of paint. The screw
threads must make metallic contact to the ground plane. The ground plane must
extend at least one foot radially from the Antenna.
b) After installing the Antenna, measure the DC resistance between the Antenna and the
airframe. Bonding resistance must be less than 2.5 milliohms.
c) Check that the antenna cable to Antenna connection is mechanically secure.
d) Ensure that the minimum distance between the C-2000 antenna and any antenna for
equipment operating in the 800 Mhz to 1200 Mhz frequency band (e.g. DME,
Transponder. TCAS) shall be 3 feet. minimum. The minimum distance between the
C-2000 and any other antenna shall be two feet.
e) It should be noted that the MagnaStar system is a line of sight system that operates
with equipment located on the ground. The MagnaStar antenna should not be located
in position that will be blocked by other mechanical devices in close proximity or easily
shadowed when the aircraft maneuvers during flight.
5.1.2
DUPLEXER
a) After installing the duplexer. measure the DC resistance between the duplexer and
the airframe. Bonding resistance must be less than 2.5 milliohms.
b) Check the antenna cable. transmit cable. and receive cable connections to the
duplexer.
These connections must be mechanically secure so they will not become loose
during aircraft
vibration. The SMA connectors (transmit and receive connectors) should be
tightened to 7
in-ibs of torque if using a 620317-1 duplexer.
ARTU MOUNTING TRAY
a) After ARTU Mounting Tray installation. measure DC resistance between the ARTU
Mounting
Tray and the airframe. Resistance must be less than 2.5 milliohms.
b) Check the input and exit airflow paths from the fan in the ARTU Mounting Tray.
Airflow paths
must be clear of any obstructions that could restrict cooling.
ARTU
a) When installing the ARTU on the ARTU Mounting Tray, insure that the ARTU sits flat
on the
tray and that the ARTU fully engages the guide pins in the rear of the tray.
b) Attach and tighten the turn-lock fasteners of the ARTU Mounting Tray to the ARTU.
c) Connect the ARTU Data, Power, Transmit and Receive cables to the ARTU. Insure
that
each of these connections is mechanically tight and secure to the ARTU. Connect
the ARTU
