Site preparation for GPS antenna
Introduction
This section describes how to perform site preparation for the GPS antenna.
Connection overview for GPS antenna
The GPS antenna is a receive-only antenna that requires only one antenna run. The GPS
antenna cable is terminated at the antenna support structure with a 7/16 DIN female
connector. At the antenna it is terminated with a 7/16 DIN-male connector. A gas tube
surge protector with DIN male/female connectors must also be installed. A jumper cable
connects the GPS antenna surge protector to the GPS antenna connector on the 9927
Distributed Base Station Outdoor Cabinet.
GPS cable connectors and surge protectors must be rated IP-67 or better. (IP-67 rating
requirement, as defined in IEC 60529, specifies total protection against dust and
protection against submersion in water.)
A side view of the GPS antenna connections are shown in the following diagram.
Recommended GPS antenna cable
Important!
The recommended cable type should be outdoor (UV) and riser (fire
retardant) rated.
The following table provides information for the recommended GPS antenna cable type.
