  • Coaxial Cable Leakage

    Bench Test Fixture July 2012Verification of FixtureMeasurementsConnector MountingBuilding Entrance PanelData for common mode current ingress into cables is mostly non-existent. The data that is available is not very useful, because test method details are not readily available. A manufacturer might tell us shielding effectiveness is so many dB, but what does that really mean? Another problem is the abundance of opinions and advice regarding shields and shielding, and generalizations about what does what inside a cable, including functionality or operational contribution of shields and foils inside a cable. Advice and information in amateur radio circles seems to be based on opinions, observations, or feelings about VHF or UHF performance, or how audio cables work. Thinking about this problem, as it relates to amateur radio, I decided to build a fixture to directly measure coaxial cable ingress from common mode shield currents. Building a fixture for lower frequencies is not that difficult, because groundplanes and shields are very predictable. They are easy to test and verify. The con...
