Detecting ingress of a transmitted signal into a cable communication system due to a radio frequency signal transmitted from a moving vehicle and interrogation of transmitter location over a separate wireless link provides monitoring of shielding integrity or flaws there in a cable communication system. The location of a shielding flaw may then be precisely located in a closed loop fashion without risking overload of the cable communication system or interference with upstream signaling therein by detecting ingress signal strength and controlling transmitted signal strength while providing a user-perceptible indication of ingress signal strength which is compensated for the control of transmitted signal strength and thus indicates proximity of a hand-held instrument or transmitter to said shielding flaw.
