PIM Foil is a light weight, temporary RF barrier that can be deployed on rooftops, both in front of as well as behind base station antennas to help isolate sources of Passive intermodulation (PIM).
When PIM Foil is placed over an external PIM source, PIM from that source typically reduces by >30 dB. PIM Foil not only helps validate the exact location of external PIM but also show the level of improvement that could be achieved with a permanent repair.
