2. Lightning arrester - Wikipedia

   en.wikipedia.org/wiki/Lightning_arrester

   Powerline worker performs maintenance of a lightning arrester on an electrical transmission tower in New Brunswick, Canada. A lightning arrester (alternative spelling lightning arrestor) (also called lightning isolator) is a device, essentially an air gap between an electric wire and ground, used on electric power transmission and telecommunication systems to protect the insulation and ...

3. Surge protector - Wikipedia

   en.wikipedia.org/wiki/Surge_protector

   Quarter-wave coax surge arrestors have coaxial terminals, compatible with common coax cable connectors (especially N or 7-16 types). They provide the most rugged available protection for RF signals above 400 MHz ; at these frequencies they can perform much better than the gas discharge cells typically used in the universal/broadband coax surge ...

4. Utility pole - Wikipedia

   en.wikipedia.org/wiki/Utility_pole

   [4] [5] It provides similar protection in case of flashovers and lightning strikes. A surge arrester (also called a lightning arrester) may also be installed between the line (ahead of the cutout) and the ground wire for lightning protection. The purpose of the device is to conduct extremely high voltages present on the line directly to ground.

5. Lightning rod - Wikipedia

   en.wikipedia.org/wiki/Lightning_rod

   A lightning arrester is a device, essentially an air gap between an electric wire and ground, used on electric power systems and telecommunication systems to protect the insulation and conductors of the system from the damaging effects of lightning. The typical lightning arrester has a high-voltage terminal and a ground terminal.

6. Grounding kit - Wikipedia

   en.wikipedia.org/wiki/Grounding_kit

   Grounding kits for different diameters Part of a tin-plated ripple. Grounding kits / Earthing kits are composed of two main components, a clamp and a cable. The clamp will be screwed on a coaxial cable and in case of lightning strokes in the antenna installation, the voltage will be diverted over a ripple in the clamp with the combined cable and will be earthed / grounded by this way.

7. Faraday cage - Wikipedia

   en.wikipedia.org/wiki/Faraday_cage

   The shield of a screened cable, such as USB cables or the coaxial cable used for cable television, protects the internal conductors from external electrical noise and prevents the RF signals from leaking out.
