An electrical continuity apparatus for a coaxial cable interface port including an interface port, a cable connector, and a resilient member. The interface port includes a first end having a threaded outer surface, and the cable connector includes a coupler having a threaded inner surface. The coupler is configured to rotatably couple the threaded inner surface with the threaded outer surface of the first end of the interface port. The resilient member is arranged between the interface port and the cable connector and urges threads of the threaded inner surface of the coupler into engagement with threads of the threaded outer surface of the interface port to provide electrical continuity between the coupler and the threaded outer surface of interface port even when coupler is loosely tightened to the interface port.
