ConcealFab’s PIM Blankets™ are temporary RF barriers that can be deployed on rooftops, both in front of as well as behind base station antennas to help isolate and reduce sources of PIM. When a PIM blanket is placed over an external PIM source, PIM from that source reduces by >30 dB. PIM blankets not only help validate the exact location of external PIM but also show the level of improvement that could be achieved with a permanent repair. Reference Anritsu application note 11410-00992A, Identifying Sources of External PIM for additional information.
ConcealFab’s PIM blanket is designed for field use and will resist punctures and tears when dragged across abrasive roofing materials. Tie-down points are provided at each corner to help secure the blanket in windy test conditions. A variety of standard sizes are available to support different test scenarios.
