Mobile WiMAX/TD-LTE RRH-2WB Installation Manual/Ver.2.0© SAMSUNG Electronics Co., Ltd. 3-29Checking Feeder ConnectionAfter connecting the feeder cables, perform the continuity test and feeder cable return lossto check if the feeder cable is changed and measure VSWR of antenna and feeder cable.Measure all cables of section ~ . The measured VSWR should be the specificationvalue or less. If the VSWR exceeds the specification value, disassemble the connector andmeasure each section separately.Checking VSWR for Minimum Cable Bend Radius and Length of RF CableIf the VSWR value for minimum cable bend radius and length of RF cable is notapplied, system may not work properly because RF signals cannot transmit orreceive smoothly. So, the VSWR value for minimum cable bend radius and lengthof RF cable must be checked and applied.RF Cable Identification Tag InstallationAttach the identification tape in the below table to the RF cable.Table 3.9 RF Cable Identification TagCategory DescriptionInstallation position Attach the identification tag to the both ends of the antenna.Materials Use the material of aluminum coated by vinyl for the identification tag.Fixing method - Antenna side: Attach the tag to the feeder line using binding stringsthrough the two holes on the tag.- Equipment Side: Cover up the feeder line with the tag and fix it usingbinding strings through the two holes on the tag.Identification method The markings must be prevented from being erased by using reliefengraving or coated labels.Connection Part of System ExternalInterface Connector Antenna
