A lightning diverter system configured to equip a radome of an aircraft comprises a segmented strip configured to transmit lightning by ionization of the air to a point of junction with the aircraft structure. The segmented strip is configured to be installed on an inner wall of the radome. The lightning diverter system comprises at least one metal block configured to be installed in a through-hole of the radome, so as to be flush with an outer wall of the radome opposite to the inner wall and which is configured to be subject to an airflow when the aircraft is moving. The arrangement of the segmented strip and of the metal block or blocks is such that, when the lightning strikes the metal block on the outer wall of the radome, the lightning is transmitted to the segmented strip on the inner wall of the radome.

The invention pertains to a dual telescoping lightning diverter system comprising a first telescoping lightning rod assembly and a second telescoping lightning rod assembly. The second assembly is nested within and operatively coupled to the first. Both assemblies are concentrically aligned, enabling them to move between an extended configuration, for increased operational height, and a retracted configuration for compactness and ease of storage. The system includes various features such as independent grounding paths for each assembly, a conductive break between the two assemblies, and an automatic transition mechanism. This mechanism is controlled by environmental parameters, particularly the detection of static charge. Additional features include threaded sections for secure engagement of the telescoping segments and a hierarchical structure of the telescoping segments for efficient extension and retraction, ensuring the system's adaptability and functionality in various settings.

A grounding rod having an elongated metal rod, an adjustment member, and a bracket. The bracket is attached to a metal portion of a piece of machinery. The adjustment member is mechanical, electric, or hydraulic and raises and lowers the elongated rod from a transport position where the elongated rod does not engage the ground, to a lowered position where the elongated rod is pushed into the ground.

The present apparatus, system and method solves the problems of the prior art by enabling substantial dissipation of an electrical energy surge coming from communications antenna which has been struck by lightning. The apparatus is for mounting to an exterior of a building at or near communications antenna also located at the exterior of the building. The apparatus is connected with incoming coaxial cables extending from exterior mounted antenna and with outgoing coaxial cables which extend from the apparatus to communications equipment housed within a communications center. The lighting strike surge travels from antenna, along the incoming coaxial cable and is redirected within the apparatus by polyphasers which trip at capacity to redirect the surge to three separate grounding bars and prevent the surge from continuing along outgoing coaxial cables leading to communications equipment thus safely dissipating surge and shielding communications equipment.
