Antenna Branch alarm in NOdeB level

[rama1234]

check the feeder

[MAZ29]

if you are using RRUW or RRUS 01 or RRUS 11 , you need to ((((REMOVE )))) the (right sign ) from (((( RIU ))) ..ie uncheck RIU when you enter ((( Site Script ))) ....
as you are not using RIU with those types or RRUs which is the root cause for this alarm ........

the effect of this alarm if the above mentioned is the cause is nothing .... Just make Sure that VSWR at each sector is above 15 dbm ........

hi everyone, I'll explain how to obteined vswr from a nodeB E*******,
you should load the nodeB with
> lt all
then
>lh ru fui get vswr

NODE0001_B_IP_850> lh ru fui get vswr

=============================================================================================
$ lhsh 000900/port_0_dev_9 fui get vswr
0009p0d9: vswr: 15.2[dB] à VSWR = 1.42
=============================================================================================
$ lhsh 000900/port_1_dev_10 fui get vswr
0009p1d10: vswr: 19.5[dB]
=============================================================================================
$ lhsh 000900/port_2_dev_11 fui get vswr
0009p2d11: vswr: 19.1[dB]

here you have the db loss and you have to convert to the value of VSWR, in this case the vswr from sector A is 1.42
to convert the initial value you can use a convert calculator online or a "spinn vswr" searching on google

I use
perfect <=1.2
1.2 < good < 1.3
bad > 1.4
