Surge protection for antenna systems
Antennas and radio link systems are particularly susceptible to surge voltages due to their location and design. They are often directly exposed to lightning and atmospheric interference. Antenna cables are often long and can distribute surge voltages from one building to another. In order to minimize damage with regard to electromagnetic compatibility (EMC), conductors with a coaxial structure are generally used. Nonetheless, the danger of surge voltage coupling in antenna cables and the formation of parasitic voltages up to the sensitive interfaces of the transceiver systems is not prevented.
Protection for systems with 7/16 connection
In order to be able to transmit high HF capacities, the solid 7/16 connections are frequently used. This connection technology is often found in German mobile phone networks. The COAXTRAB C7/16-UB-280DC-SB-SET (Order No. 28 81 54 4) now provides lightning and surge protection that helps to avoid damage to systems with this type of connection in the event of surge voltages due to lightning. Surge current impulses with up to 20 000 A (8/20 µs), or 2 500 A (10/350 µs) are kept well away from the transceiver by the COAXTRAB surge protection.
