The coaxial cables enable impulsive electromagnetic fields, which generate induction peaks, to unimpeded reach the electrical devices.
The resulting overvoltages destroy the electrical equipment connected to the antenna, such as head-ends, multiswitches, LNBs, receivers and TV sets.
With POLYTRON’s inline surge protection OV-F, this danger can be minimized.
