Finding Shorts In Coaxial Cable.
Finding Shorts In Coax – We are having some trouble with a legacy analogue CCTV system the user wants to retain because they value zero latency – could it be a short and how would we find it?
A: Disconnect the coax at each end and use and ohmmeter to test from a connector case to a centre pin. You want to see infinity and if you don’t, there’s a short. Shorts in coax usually take place at BNCs or at right angle bends, so keep an eye out for culprits in the run.
Another coaxial cable test is to clip a test terminal to the cable pin and the case of a connector at one end and then to scamper down to the far end of the cable and test for resistance.
You want to see a reading around zero – anything more means than this means your cable is experiencing resistance from crummy connections or corroded sections of cable.
