C. Get Access
(1) For the location of this component, refer to paragraph Component Location
(Ref. AMM D/O 46-41-00-00).
(2) Make sure that the STEPLADDER 1.0 M (3.3 FT) is below the related ceiling panel(s) between FR24 and FR26.
(3) Make sure that the related ceiling panel(s) between FR24 and FR26 is (are) removed (Ref. AMM TASK 25-23-41-000-001).

4. Procedure
Subtask 46-41-71-420-050-A ** ON A/C NOT FOR ALL

CAUTION: OBEY THESE PRECAUTIONS TO PREVENT ELECTROSTATIC DISCHARGE (ESD) DAMAGE TO THE COMPONENTS:

STAY ON A CONDUCTIVE SURFACE THAT IS ELECTRICALLY GROUNDED.
USE A CONDUCTIVE WRIST-STRAP THAT IS ELECTRICALLY GROUNDED. (CONNECTED TO A BONDING-POINT NEAR THE WORK AREA).
BEFORE YOU USE THE TOOLS, MOMENTARILY HOLD THEM AGAINST AN ELECTRICAL GROUND TO RELEASE STATIC ELECTRICITY.

CAUTION: DO NOT TOUCH THE CONNECTOR PINS OR OTHER CONDUCTORS ON THE COMPONENT DURING THE PROCEDURE. IF YOU TOUCH THESE CONDUCTORS, ELECTROSTATIC DISCHARGE CAN CAUSE DAMAGE TO COMPONENT.

A. Installation of the cellular-gatelink antenna

Cellular-gatelink antenna ** ON A/C NOT FOR ALL

(1) Clean the component interfaces and the adjacent area.
(2) Do an inspection of the component interfaces and the adjacent area.
(3) Put the coaxial cable into the hole of the bracket (2) thru the dedicated groove.
(4) Put the cellular-gatelink antenna (1) in the installation position in the bracket (2) and install the lock washer (3) and the nut (4).
(5) TORQUE the nut (4) to between 7.37 and 6.03 m.N (65.22 and 53.36 lbf.in )

.
(6) Prepare the surface of the bonding point(s) (Ref. AMM TASK 20-28-00-912-803).
(7) Put the connector assembly (7) in the installation position in the bracket (8) and install the screws (9), the washers (6) and the nuts (5).
(8) Tighten the screws (9).
(9) Do the electrical resistance measurement and the final protection of the bonding point(s) (Ref. AMM TASK 20-28-00-912-802):
(a) Make sure that the bonding contact resistance between the cellular-gatelink antenna (1) and the bracket (2) is not higher than 5 milliohms (Ref. AMM TASK 20-28-00-912-802).
(10) Remove the CAP-BLANKING from each electrical connector and receptacle.
(11) Make sure that all the electrical connections are clean and in the correct condition.
(12) Connect the coaxial connector (10).

WARNING: USE PROTECTIVE GOGGLES AND GLOVES WHEN YOU REMOVE OR INSTALL LOCKWIRE. EACH TIME YOU CUT LOCKWIRE, REMOVE AND DISCARD IT IMMEDIATELY. LOOSE LOCKWIRE CAN CUT YOU OR MAKE YOU BLIND, AND/OR CAN CAUSE DAMAGE.

(13) Safety the coaxial connector (10) with 14QDB1Wire-Locking Dia: 0.5 mm (0.020 inch) CRES Nickel Alloy -.
