Hello friends!
In ericsson 2G cabinets,we usually gets alarm for RX diversity sometimes even when we use both ports of antenna.It is npt service affecting but how can we kill this alarm.
Thanks
it happens if you have a crossed feeder towards the antenna.. check it simultaneously.. I mean, have someone upstairs to check the feeder connection.. try to do DTF with a dummy load to see which feeder you are testing. if he picked the wrong one, of course you will get a VSWR of the whole antenna system.. so you’ll have to do it 1 by 1.. the cell A TX/RXA leg is not paired with Cell A RXB. it means the right diversity is paired with the other sector..
when you reset the TG or halt the station it will appear again at least 1 hour. (if u cant rapair ant. system). never leave the site if u dont sure to fixing site
sure it will come back. so better have sitemaster or equivalent in troubleshooting.. it makes also handy when you have a netmonitor to check whether your BCCH is on the right sector/cell.. have fun! goodluck

It worked out.It was an RDU with so many cables.I spent like 3 hours to trace the correct cable.Some other cable was attached to the antenna 🙂
