Remote GPS Receiver Cabling
The remote GPS (RGPS) receiver is connected to the junction panel using one of the three
standardized cables or a customer provided alternative.
RGPS Cables
The RGPS receiver cable has to be a shielded cable.
The screen has to be grounded through the metal shell of the D type connector. However, it is required
for the cable screen to be connected also to the site ground where the cable enters the building.
It is similar to the grounding applied to the RF cables. See Motorola Standards and Guidelines for
Communications Sites, R56.

RGPS Surge Protectors
Use the modular data surge protector (Part Number: GMDN0889A) for the remote GPS cable, shown
in the following figure. The surge arrestor must be installed on a grounding plate, or a ground
connection stud added to the side of the box.

NOTICE: The duplicated Supply and GND connections should be joined together at the surge
protector.
