How do you test a coaxial cable for continuity?

Using a multimeter to check for resistance is the appropriate method for testing a coaxial cable for continuity. This process involves measuring the resistance across the center conductor and the shield of the cable. If the cable is in good condition, there should be a low resistance reading indicating that the circuit is complete.

If there is no continuity, or if the multimeter shows an open circuit (infinite resistance), it suggests there may be a break or fault in the cable. This technique allows for assessing whether the coaxial cable can adequately carry signals, which is crucial for reliable data transmission in telecommunications systems.

Visual inspection, while helpful for spotting physical damage, does not provide a definitive measurement of continuity. A voltage tester is more suited for checking live circuits and not the integrity of cable pathways, while connecting the cable to a signal booster does not directly test continuity and risks damaging the equipment if the cable is faulty.
