This handy tester is designed for satellite, cable and security camera installations.  It tests multi-run coax cables terminated with F-connectors from a central source.  It has the ability to put a tone signal on a coax cable, as well as find and identify multiple coax cables connected to a coax splitter.  Individually-identified test terminators allow you to trace and identify up to 4 drops at a time from the main cable box.
