g. Equipotential busbar, e. However, the air-termination rod struck, surge voltages will coupled. this case, the risk direct lightning strike in the SAT cables almost zero. 1801 VDE 5015650 Coaxial surge protection, e. Ideally, the finished lightning protection system the satellite antenna should loc- ated within the protective angle the air-termination rod. 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.Satellite systems according IEC/EN 60728-11 Satellite systems and antennas are often exposed locations roofs, next the air-termination rods.

Here, is vital that the required separation distance (s) main- tained between the air-termination rod and the an- tenna system
