How to "tone out" a coaxial cable

Have you ever installed a bundle of coaxial cable and lost track of which cable was which? Here is an easy way to identify a cable. Short out a SO-239 panel mount by connecting the center connector to the ground side as shown in the photo. Install the SO-239 one end of the cable in question and then check the continuity on the other end of the cable with a VOM or tone tester.
