The Channel Master Coax Cable Tester is designed to test and identify coaxial cables for continuity, opens and shorts. The Coax Cable Tester is one of the most useful tools for installing a TV antenna when using existing pre-wired coaxial cables. The tester will enable you to determine the correct coaxial cable(s) to connect to your antenna. The Coax Cable Tester is made up of two parts, the signal/tone generator and the speaker, and it's easy to use. Simply connect the signal/tone generator to a coaxial cable located anywhere in the home then take the speaker to the distribution point or structured wire panel and connect to each of the coaxial cables, when the correct cable is identified, you will hear a high pitched tone from the speaker. The Signal/Tone Generator part of the tester also has a built-in red LED indicator which will illuminate when the speaker is connected at the other end or when a short is detected in the coaxial cable.
