3.1.5 Coaxial cable and Antenna Connection
- The coaxial cables which are connected to antenna distribued network connect to
antenna port of ROU. Before connection, check the VSWR value of coaxial cable
whether it is within specification using SITEMASTER .
- At this time, check if the Return loss have above 15Db or VSWR have below 1.5
- The part of antenna connection fasten to port not to be loosed and not to be injected
the dusty and insects
- The antenna connected to ROU is only serviced in inbuilding
3.1.6 Insertion of RDU
ROU has slots to enable up to three RDU modules to be inserted into the unit.
You can insert a RDU into any slot. It is not possible to provide services with a RDU
module alone; you need to connect the module with Cavity BPF in any case.
The table below shows types of RDU and CAVITY BPF:
