Abstract

When coaxial cables are connected via ordinary multiway connectors, inductance is introduced in series with the outer-conductor connection, causing unwanted self-induced voltages and a reduction in the shielding action. This is reduced by the use of ferrite toroids around inner and outer connections to a coaxial cable to provide a cancelling negative inductance. The best types of coaxial cable connector make contact to the cable braid all the way round its periphery, so that the coaxial conductor configuration is maintained right through the connector. However, today it is very common for coaxial-cable connections to be made through ordinary multiway connectors, each outer conductor being taken to a single pin.
