- The coaxial cables which are connected to antenna distribued network connect to
antenna port of L2ROU. 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 L2ROU is only serviced in inbuilding
