Abstract
Low-PIM polymeric cable support brackets are used to support cables feeding antennas and other types of equipment at cellular base stations (cell sites). A variety of polymeric mounting brackets, cable ties, cable support blocks, and stackable hangers are used to eliminate loose fitting metal-to-metal contact points that tend to create PIM. The mounting bracket body may include standoff features allowing the same bracket to securely attach to poles of different diameter, an external hex profile for receiving a wrench, and a fitted receptacle for receiving a bracket end fastener to facilitate installation. Polymeric cable ties fed through cable slots in the mounting bracket may be positioned to prevent the bracket end fastener from falling out of the fitted receptacle. The low-PIM cable support brackets are suitable for use within one carrier wavelength behind and around base station antennas where conventional cable brackets have been identified as problematic PIM interference sources.
