This surge protector is intended for antenna systems and cable TVs, but can also be used in satellite systems. The surge protector has a DC passage and is suitable for the frequency range of 5 to 2200 MHz. It is equipped with a self-healing varistor and remains intact even after overvoltage. The component has a quick response time and can hold up to 4500 A (8/20µs). High electrical voltages can occur in thunderstorms and enter the cable network via antennas or in the ground. With the Axing SZU 6-01, you can effectively prevent damage to the components connected to the coaxial cable. With a voltage spike, the connection is short-circuited and cannot damage subsequent components. The TV and radio signal remains virtually unaffected in normal operation. The passage loss is maximum 0.5 dB, the return loss at least 20 dB. Thanks to the metal housing and high-quality connectors (IEC plug and IEC socket), high shielding of over 90 dB is ensured and meets class A. The surge protector can be plugged directly onto the inputs of an amplifier or distributor. Earth angles and potential compensation can also be complemented perfectly.
