A lightning surge dissipation apparatus for mounting to a building exterior and for connection with coaxial cable extending from communications antenna located on the building exterior and with coaxial cable extending to communications equipment located within the building interior, the apparatus comprising:
- an electrically insulated enclosure having top, bottom, right, left, front, and back side walls, each wall having an interior and exterior surface, the front side wall having an opening configured for closure by a door, the enclosure defining an electrically insulated interior space;
- an electrically insulated door configured for opening and closing the opening, the door mounted to the exterior surface of the front side of the enclosure using a hinge;
- an insulated universal power box disposed within the interior space of the enclosure, the power box containing a power supply apparatus and connecting electrical and grounding wires which extend from the power supply apparatus mounted within the power box through an insulated conduit, the conduit connected with the power box and extending downward through the interior space of the enclosure and connected with an insulated outlet connector at the bottom side of the enclosure;
- at least one DIN rail power supply module mounted with the interior surface of the back wall of the enclosure, the power supply module connected with and drawing power from the power supply apparatus;
- at least one high capacity polyphaser mounted on a first grounding bar, the first ground bar mounted with and insulated from the interior surface of the back side of the enclosure, the at least one polyphaser passively grounded to the first grounding bar, polyphaser having a power inlet connected with and accepting power from the DIN rail power supply module, an incoming coaxial cable port configured for connecting with an incoming coaxial cable, and an outgoing coaxial cable port configured for connecting with an outgoing coaxial cable;
- a second grounding bar mounted to and insulated from the interior back side surface of the enclosure, the second grounding bar connected with the first ground bar by ground wire, the second grounding bar positioned separate from but adjacent to the first grounding bar, the second grounding bar having substantially better conductive properties including mass than the first grounding bar;
- a third grounding bar mounted to and insulated from the interior back side surface of the enclosure, the third grounding bar connected with the second grounding bar by ground wire, the third grounding bar positioned separate from but adjacent to the second grounding bar, the third grounding bar having substantially better conductive properties including mass than the first grounding bar;
- a ground wire connected with the third grounding bar at one end, extending through an insulated opening in the bottom side of the enclosure;
- a ground wire connected with the third grounding bar at one end and extending to and connected with the interior surface of the door;
- at least one incoming coaxial cable extending from one or more communications antenna mounted on a building exterior and inserted through insulated boots located at one wall of the enclosure, the inserted end of the input cable attached to the incoming coaxial cable port the polyphaser;
- at least one outgoing coaxial cable connected to the outgoing coaxial cable port of the polyphaser at one end, the opposite end of the outgoing coaxial cable extending through an insulated connector at one wall of the enclosure;
- wherein upon a lightning surge entering the enclosure through the input coaxial cable, the polyphaser breaks circuit at capacity threshold, directing the surge into the first grounding bar, the surge then traveling from the first grounding bar to the second grounding bar, and from the second grounding bar to the third grounding bar thus substantially and effectively dissipating the surge within the enclosure and shielding the surge from the outgoing coaxial cable leading to the communications equipment.
