300 BTS Hardware Installation, ATP and FRU Procedures
PRELIMINARY
Objective
The objective of this procedure is to show how to install the Remote
Global Positioning System (RGPS) head.
Tools and Materials
One RGPS Head (Motorola Part Number 0186012H03) is required to do
this procedure.
Installation Procedure
The RGPS head must not make contact with any metal
surface other than the provided hardware. Use only the
equipment provided to mount the RGPS head. Failure to
do so could damage the RGPS head.
CAUTION
Table 3-11 and Figure 3-9 show the procedure for installing the RGPS
head.

Step
Action
1
Determine the mounting location.
NOTE
The RGPS head mounting location is critical to the operation of the BTS. Position the RGPS
head to have an unobstructed view of the sky and to minimize the chance of debris (leaves, dirt,
etc ) accumulating on the radome of the RGPS head Place the RGPS head as far away from the
etc.) accumulating on the radome of the RGPS head. Place the RGPS head as far away from the
BTS transmit antenna as possible to avoid RF interference issues.
Do not install the RGPS head close to a lightning rod. A lightning rod attracts lightning, which
can damage or destroy the RGPS head. Also, since a lightning rod is connected to an earth
ground, it can act as a shield and create a shadow that may block or reduce the signal from a
satellite.

WARNING
The structure of the wall should be verified by a qualified structural engineer.
Mounting the RGPS head and hardware to an inadequate wall structure and/or using inadequate
installment methods can result in serious personal injury.
2
Use the appropriate mounting bolts for the mounting surface and install the two wall mounting
brackets (shown in Figure 3-9).
3
Insert the RGPS Interface cable through the pipe so that the connector end is at the RGPS head
mounting location. (See Figure 3-9).
4
Connect the 12–pin connector on the RGPS head to the 12–pin connector on the RGPS interface
cable. To secure the connection, tighten the spinning connector flange. Make sure to provide
slack in the RGPS cable to allow future servicing. See Figure 3-9.
