Surge Protectors and DC Breaks

Mobile communication systems are constantly at risk of being affected or damaged by overvoltage, induced DC voltages, etc. Protective devices such as surge protectors and DC breaks are used to compensate for these external influences. Both have the task of protecting the connected system without interfering with its operation.

Due to their low PIM, attenuation and reflection, SPINNER products are ideally suited for the protection of mobile communication installations. Our protection devices are available with 7-16, 4.3-10 or N connectors.

Surge Protectors

Overvoltages are typically the result of electromagnetic induction as a result of events such as lightning strikes. For different applications, SPINNER offers surge protectors with gas discharge tube, λ/4 short-circuit loop or a combination or both in a hybrid surge protector.

DC Breaks

DC breaks are used to prevent direct currents and low-frequency signals from spreading, for example along railway lines as a result of induced voltages, and influencing other equipment in the vicinity.

Our DC breaks very effectively achieve this, since their inner and outer conductors are separate. Our “inner-only” models are mainly used for mobile communication antennas that are controlled by low-frequency signals.
