Surge Protection of Antenna Systems

Why Protect?

The antenna lines for the radio transmission systems are very long, they exceed the height of the buildings they stand on, and are directly exposed to lightning strikes. This applies to stand-alone antennas as well.

With long coaxial, data, and power supply lines, transient phenomena occur, which induces overvoltage to the line, which may get through the lines down to sensitive interfaces of the technologies and result in damage on the broadcasting and receiving equipment. Surge protection is important both for the radio directional transmission devices and mobile radio systems, as well as for the surveillance and inspection video systems, or in private area, e.g. satellite and TV receivers.

Safety and reliability of the broadcasting and receiving equipment of any type is substantially increased using suitable surge protections in addition to the standard protection against lightning strikes.

What to Protect?

• BTS low voltage power installation + power back-up supply unit
• HVAC unit for BTS temperature and humidity control
• Coaxial cables for antennas and parabolas with frequencies up to 3,5 GHz
• Ethernet lines for data transmissions among installed technology
