A device for grounding a coaxial cable to a ship\s hull or bulkhead having an opening for the cable, is configured to include a split metallic cone with serrated apex portions fastenable around a bared shield of the coaxial cable, and flanged base portions securable to the ship\s hull and overlying the opening, such that the split cone forms substantially 360°of coupling between the bared shield and the ship\s hull. This configuration increases the area and effectiveness of electrical contact between the bared shield and the ship\s hull while decreasing the effective inductance and overall impedance, thereby reducing the amplitude of high frequency transients caused by an externally induced electromagnetic pulse (EMP) or any electromagnetic interference source having a similar frequency range.

A grounding device for forming a grounding connection between a ship\s hull or bulkhead and a coaxial cable extending from the weather or external side of the bulkhead through an opening therein to the non-weather or compartment side thereof, the grounding device comprising: a metallic cone having a slant height and being split or formed into two halves lengthwise, each half of the metallic cone including a flanged top portion, a flared bottom portion and a slant body portion integral and intermediate each of the flanged top and flared bottom portions; means for flush mounting and securing the flanged top portion of each half of the cone to the non-weather side of the ship\s hull about a bared shield of the coaxial cable and overlying the opening; and means for gripping the flared bottom portion of each half of the metallic cone to the bared shield, thereby forming a substantially continuous 360°electrical grounding connection between the ship\s hull and the bared shield, the slant height from the top and bottom portions of each half of the cone being configured short enough, for a particular dimensioned coaxial cable, to present a low inductance and overall low impedance path for currents induced by an EMP or any electromagnetic interference source having a similar frequency range in an external length of the coaxial cable.
