2.5.1.2 External RF Antenna Connection
Two N-type connectors are used for external antenna connection. The connectors
should have impedance 50Ω and be lightning protected.
2.5.1.3 GPS Connection
A TNC connector is used for GPS antenna connection.
GPS In and GPS Out Connectors: The neighbouring BTSs can be synchronized by
single GPS source when chain connection is used . Two RJ-45 connectors are
used for GPS synchronization: GPS-IN is an input from previous BTS and GPS out
as an output to next BTS.
