1801 VDE 5015650 Coaxial surge protection, e. 4+1 5083400 Fine protection device for SAT and 230 supply line, e. Equipotential busbar, e. Using, for example, surge protection device like the OBO 4+1 (for protecting, for example, multiswitches) FC-SAT-D (for protect- ing set), these surge voltages can limited a level that safe for the device question. this case, the risk direct lightning strike in the SAT cables almost zero.

Ideally, the finished lightning protection system the satellite antenna should loc- ated within the protective angle the air-termination rod. However, the air-termination rod struck, surge voltages will coupled.g. Here, is vital that the required separation distance (s) main- tained between the air-termination rod and the an- tenna system.g. The following figures show the lightning and surge protection for satellite system: Device Item no. For this reason, air-termination rods must used pro- tect these systems against direct lightning strikes, to prevent them from serving lightning air-termination systems themselves
