Abstract: A signal detection apparatus includes a signal reception unit, an Analog to Digital (A/D) signal processing unit, and a user interface unit. The signal reception unit receives an external signal. The A/D signal processing unit determines whether the received signal is an abnormal signal based on a plurality of signal profiles having different signal characteristics, and obtains the abnormal signal if, as a result of the determination, it is determined that the received signal is the abnormal signal. The user interface unit displays the abnormal signal.

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.
