Hi, I have one 3G sector with vswr alarm… I changed RRU, changed the cable connecting the RRU to the antenna but the alarm won’t clear… Has one parameter to affect this issue?
Check if it’s connected to right antenna band
What is the threshold of VSWR alarm ?
check connectors are well tightened
can also use a site master
It’s connected to the right antenna band
in ericsson VSWR=1.5 for 100% sensitivity
1.10 and 1.15 also acceptable
its alarm tHreshold which i shared , acceptable value defined by operator.
If you changed jumper, RRU and still have the alarm, then the antenna port is causing the high VSWR. Try to connect the jumpers of this sector to another antenna, just check if the VSWR will appear.
OK. Thank’s! Will do that
