Abstract:
1. A method of determining the location of an ingress of errant signals into a cable system, comprising the steps of: providing a transmitter and an antenna, for radiating an electrical signal of a desired frequency; providing a shielded receiver at the cable entry location of a test site, said receiver having a tuner, signal detector and a display reactive to signals of a particular frequency passing solely through the cable system of said test site; providing an activation encoder and an activation transmitter in said receiver, and providing an activation receiver and an activation decoder in said transmitter, such that when it is desired to test said cable system, said receiver may signal said transmitter and said transmitter may activate said receiver and then radiate said signal of a desired frequency; and radiating a signal of said particular frequency and observing said display for reaction.
