Reply To: IBS and DAS


Hi Ashok,
There is no problem measuring VSWR inclusive of all these passive components.Make sure that your site master is calibrated to the Frequency band used by the RBS before performing the measurements.
Try to consider the DTF function of the Site Master/VSWR meter as suggested by David, from here you will have a better reference on which part of the DAS segment is causing the high VSWR.
Keep in mind also the bending of your feeder cables, different size of cables has their own bending radius which could contribute to high VSWR measurement if not followed.
