Antenna System Fault Finding

NG Rigging have completed PIM analyser and Sitemaster testing on approximately 1200 O2 sites ranging from December 2010 to August 2012, the majority of these sites tested were completed on the O2 U900 build project.

Since the beginning of 2012 we have attended approximately 500 U900 sites to complete PIM fault finding & remedial works, some of these sites have been experiencing a variety of problems including high PXR and VSWR levels, this can result in an increase in dropped calls.

NG rigging teams can quickly identify faults within the system using the PIM analyser and Sitemaster test units, also our rigging vans carry enough stock to cover almost any faults identified on site including spare combiners and antennae, the end result is 70-80% of sites are left clean and green on the first visit.
