With this compact dgtct04 4-way coaxial cable mapper from digiwave, users can find and identify multiple coax cables and tests for opens and shorts. It is a hand-held device for catv and security system installers who test multi-run coax systems terminated with f-connectors, or those who wish to map runs to a central bundle. It can be used to put a tone signal on a coax cable. Additionally, with four individual remote terminators, the digiwave dgtct04 is ideal for mapping coax installations.
