Chapter 5: Antenna Installation Procedures Measure VSWR and Return Loss Voltage standing wave ratio (VSWR) is a ratio of the maximum to minimum voltage as measured along the length of a mismatched RF transmission line. VSWR indicates the level of impedance matching between RF equipment (such as amplifiers, cabling, and antennas). When the impedances of the RF equipment are mismatched, some of the RF energy is reflected back along the transmission line.
Macro Base Station Installation Procedures (NPM-1000) 3 Carefully disconnect the RF equipment and cables you want to test. W A R N I N G : Extreme care must be taken when connecting or disconnecting the ! 4 coaxial antenna cable to avoid damage to the center pins. Connectors should be torqued to a maximum of 17 foot-pounds and be free of dirt or moisture. Do not over-torque the connectors as this can damage the center pin and cause cable faults and other RF problems.
Chapter 5: Antenna Installation Procedures Measure the Distance to a Fault Distance-to-fault (DTF) is a measurement of VSWR or return loss based on distance. A DTF test indicates the distance to a short, open, or load. Perform a DTF test whenever a VSWR test reveals that the antenna system is not operating within specifications. To accurately interpret the results from a DTF cable sweep, you need to know the lengths of your cables and the location of any devices or connectors attached to those cables.
