Abstract:
1. A surge-protected coaxial termination device comprising: a. a metallic outer body having a central bore extending therethrough along a longitudinal axis between first and second ends of said metallic outer body, the central bore being bounded by an inner wall having a first axial length; b. an inwardly-directed radial step element extending from said inner wall and having a second axial length, wherein said second axial length is significantly shorter than said first axial length of said inner wall, and wherein said inwardly-directed radial step element has a reduced diameter in comparison with said inner wall; c. a center conductor extending axially into the central bore of said metallic outer body, said center conductor being in close proximity to an innermost surface of said inwardly-directed radial step element to form a spark gap therebetween; and d. air within the spark gap formed between the innermost surface of said inwardly-directed radial step element and said center conductor.
