An over-voltage protection filter like this will protect a satellite TV set up from over-voltage damage caused by thunderstorms (lightning direct or in the surrounding area) or stress peaks.
The Hama Over-Voltage Protection Filter connects to the LNB connectors, multi switches or can also connect to distribution amplifiers. Several over-voltage filters, mounted in different places will enhance security.
The connectors are F-plug and F-socket.
The Hama Over-Voltage Protection Filter can be used outside as the socket is equipped with integrated seal ring. There is DC power pass and the frequency range is 5 to 2400 MHz, 75 ohm. The transmission loss caused by adding the filter is very slight (approx. 1 dB).
