Abstract
Apparatus for protecting a coaxial transmission line using a coaxial transmission line surge arrestor and a fusible link connected thereto. The surge arrestor comprising a gas discharge tube having a hollow conductive housing and a center conductor having a longitudinal axis parallel to the direction of signal transmission, the diameter of the center conductor being varied along at least a portion of its length for matching the impedance of the surge arrestor to that of the transmission line. The fusible link comprises a section of coaxial transmission line having a solid copper center conductor electrically connected in series with the surge arrestor.

Apparatus for protecting a coaxial transmission line comprising:
- (a) a coaxial transmission line surge arrestor comprising a gas discharge tube, the gas discharge tube comprising
- (1) a hollow conductive housing,
- (2) insulating ends adapted to seal the housing,
- (3) an inert gas sealed in the housing,
- (4) a center conductor extending through the housing, the conductor having a longitudinal axis oriented in a direction parallel to the direction of signal transmission, and
- (5) the diameter of the center conductor being varied along at least a portion of its length between the insulating ends for matching the impedance of the surge arrestor to that of the transmission lines;
- and
- (b) a fusible link electrically connected in series with the coaxial surge arrestor.
