These enable transmission from a frequency (DC). These offer optimal transmission behaviour with low damping values and are connected series the transmission path. They can therefore used a wide range applications. The gas-discharge tube can additionally replaced case defect. Suitable arrestors for these applications include the DS coaxial surge arrestor from OBO Bettermann. For signals outside the frequency range sup- ported, this arrestor type galvanic short circuit. Due to the capacity the gas-discharge tube they are however limited their bandwidth: the cut-off fre- quency currently around GHz. Surge arrestors with Lambda/4 technology The second variant the surge arrestor with Lambda/4 technology.11n standard with a frequency 5. For example, no Wi-Fi signals according the 802. They are available for all standard connections.TBS Blitzschutz-Leitfaden 2018 / en / 2020/01/10 14:42:40 14:42:40 (LLExport_02613) / 2020/01/10 14:42:54 14:42:54 Coaxial surge protective device with gas-discharge pro- tector Coaxial surge protective device with Lambda/4 techno- logy These sensitive, high-frequency systems need be protected from lightning currents and surge voltages.

Coaxial arrestors come two types: With either gas-discharge protector and Lambda/4 technology.9 GHz can transmitted. The advantages this technology are its support for frequencies around GHz, and its very low protection level approximately They also re- quire virtually servicing because they not use a gas-discharge protector. Coaxial surge protective devices with gas-discharge protector The first type coaxial surge protective devices with a gas-discharge tube. The disadvantages these devices are that not possible transmit supply voltage along the sig- nal line, and their scope application generally lim- ited just one application, depending whether the necessary frequencies lie within the frequency range supported. These arrestors are band-pass filters that only pass frequencies within specific range. They are available for virtually all plug systems
