ABSTRACT:
A cable leakage detection system to be placed in a moving vehicle for monitoring signals leaking from a coaxial cable network. AM and FM RF detectors are combined with a global positioning system, a microprocessor, a storage device, a display device, and an antenna to unambiguously measure the radio frequency signal strength of an RF leak. The leakage detection system can indicate whether the leak is occurring in the left or right side of the vehicle. An operator can, by observing the unique display, determine whether the received RF energy is a leak from the coaxial cable system or a spurious signal from some other source. The cable leakage detection system can unambiguously detect an RF leak and store the vehicular leakage index, the RF signal level, the distance from the coaxial cable, the frequency of the signal, the geographic location, and the time of the detected leak.
