Hi,
You should check line feeder from nodeB to antenna, in my experience this alarm indicate VSWR, the value is > 2
In some type of nodeB you can check the VSWR value.

will be impact to voice and data quality
decrease network coverage


need to cehck VSWR ffrom feeder to antena that correct
may u can see the VSWR versus the supervisionthreshold at rbs

value antennasupervisionthreshold--see attachment value supervision vswr


may usefull for all

-------------
pass default

Hi Electron,

Usually, alarm come when RBS situation in high VSWR near the antenna,
If you using ASC, may you may check the ASC installed.

Hope help.

It's related to VSWR but other Rf parameters may also cause this alarm.
Check the Antenna connectivity.
