IM WORKING AS AN O&M ENGINEER IN KSA. MOSTLY I RECTIFY THIS ALARM BY OPEN THE FEEDER CONNECTOR CLEAN AND WET IT IN CASE OF RAINY LAND OR IF THERE IS MUCH MOISTURE OVER THERE AND THEN AGAIN RETIGHTEN. FIRST CHECK ALL THE CONNECTORS THEN RECOMMISSION THE SITE AND WAIT FOR THIRTY MIN HOPE IT WILL NOT COME AGAIN. OTHER WISE CHECK THE SECTOR SWAPING. THE LAST SOLUTION IS JUST REMOVE THE BIAS-T FROM CONNECTORS CONNECTED TO BTS.IT WL NOT COME AGAIN
