A method is provided for locating the source of a leak from a CATV system. The method comprises providing at least one instrument adapted to measure the strength of a signal carried by the CATV system, moving the at least one instrument along a route, measuring the signal strength using the at least one instrument, providing Global Positioning System (GPS) locations to associate with measured signal strengths, storing the associated measured signal strengths and GPS locations, and identifying locations in the CATV system that lie along perpendiculars to the route at local maxima of the measured signal strength.
