Coaxial cables will be used to transport analog and digital signals to and from the home. The full spectrum of the coaxial system, from 5 MHz to 1 GHz will be utilized for the delivery of video, voice and data. The natural shielding characteristics of coaxial cable will play a primary role in helping to maintain signal integrity and ensure error free transmission. This paper addresses the shielding performance of coaxial cable and its related components. This is accomplished through a discussion of leakage mechanisms and laboratory shielding tests.
