Connecting antennas
Overview of
antenna
connections
The components shown in Figure 3-10 provide all the RF connections to the
cabinet and internally within the cabinet. Up to four cabinets can be
interconnected to form a single BTS site.
Site configurations supplied by Motorola have appropriate earth, expansion or
blanking plates fitted and all internal RF cables supplied. Antennas need only be
connected to the earth/connector plate as all RF connections internal to the
cabinet, (those between CTUs, Tx blocks, SURF and earth/connector plates),
are cabled correctly for the cabinet configuration supplied.
Multiple cabinet configurations have additional RF cabling, stored, for shipping,
in the master cabinet. These cables will need to be routed to the expansion
cabinets and connected as shown in the Suggested RF configurations
Variations in site layout and RF configuration may require the fitting of left side
cable entry earth plates and/or expansion plates.
