  • Patent number: 11145965
    Abstract: 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.
