Abstract: An antenna line protection device includes a pair of coaxial connectors and a streamer discharge module. The pair of coaxial connectors are disposed on both side ends of the antenna line protection device. The streamer discharge module is coupled between the coaxial connectors so that, when a pulse signal is input via the coaxial connectors, the streamer discharge module induces an electric field and thus establishes a discharge current channel, thereby suppressing an excessive input pulse.

Abstract: A waveguide feedthrough for broadband electromagnetic wave attenuation is provided in an electromagnetic wave shielding structure, in which data processing and communication devices are installed, so that a plurality of optical cables or the like which are connected to data processing and communication devices are led into the electromagnetic wave shielding structure through the waveguide feedthrough. Thereby, broadband electromagnetic waves generated from external other devices can be prevented from entering the electromagnetic wave shielding structure. For this, the waveguide feedthrough includes a waveguide feedthrough body which is made of conductive material and has a through hole therein, and an electromagnetic wave absorber which is provided on an inner side surface of the through hole.
