What are some key terms for lightning protection?
Air Terminals- Inconspicuous slender rods installed on a roof or a tower as defined by industry standards. In some cases, the rods are placed on a tower leg opposite to the one on which the radio is mounted. This is to direct the lightning strike away from the equipment.
Conductors- Aluminum or copper cables that interconnect the air terminals with the other system components (such as copper grounding plates).
Ground Terminations- Metal rods driven into the earth to guide the lightning harmlessly to the ground (usually steel with copper cladding).
Surge arrestors and suppressors- These are devices that are installed in conjunction with a lightning protection system to protect electrical wiring and electrical systems equipment. These devices should be installed at intervals along the leg of a tower and at the point of entrance of a cable into a building.
