DEHNgate – SPDs for Coaxial Connection
Lightning Current and Surge Arrester
- Universal surge and combined arresters
- Maximum discharge capacity for coaxial systems
- Low voltage protection level allows to protect terminal equipment
- Contact materials with extremely long endurance
The space-saving DG A FF TV can be mounted onto a DIN rail to protect satellite systems with several outputs. For single applications such as broadband cable connections, the device can be simply snapped into a wall-mounted adapter. Two F connections are also included.
The quarter-wave surge arresters are bandpass filters. Only signals within a defined frequency band are transmitted. Since lightning interferences have a low frequency spectrum, the shorting stub acts as a short-circuit, conducting the lightning current to the ground. This makes the surge arresters mechanically very robust and almost maintenance-free. Due to their low voltage protection level and high discharge capacity, they can be used as combined lightning current and surge arresters. If additional remote supply is needed for the antenna, a combination of a gas discharge tube and quarter-wave technology (DGA LG) should be used. The arresters are made of top-quality materials and give outstanding endurance.
