Abstract
A method and system for implementing a passive intermodulation (PIM) coaxial protection circuit is provided. An electrical circuit is created between a radio source, coaxial cable, and antenna to prevent passive intermodulation. The radio source or an external power supply provides direct current and voltage in the electrical circuit, causing the current and voltage to pass through any corrosion that might build up in the path, especially at connectors.
