i am getting the alarm-rx level differ too much between main and diversity antennas ”
i have checked all internal cabling,trx but still the alarm comes.
what can be the reason and how to rectify
If u r getting this alarm on specified TRXs (One) u can swapp this TRX with another one (Same Type -TSGB,A,TRXA,D …etc) if the problem will be transferded to with this TRX u have to chenge the TRX!!
Otherwise u have check all cables and jumpers and the connectors every where.
Of course u can do the above after VSWR checking, if its good u can only swapp the TRXs.
Tell me please where exactly u r getting this alam?On whole sector, segment, BTS, or only on one TRX?!
Dear chinmay ,
Did u check the VSWR?if yes,is it normal?
Yes u can swapp the Duplexer (DVGA,DVDA)with another one wich is working normal,and again if the plroblem will transfered means u have to replace the DVGA with new one.and swapp also the multicopler but be sure to swapp it with another one,different sector,means swapp the DVGA in sector and the multicopler in other sector to deploy them in diffirent sectors.
