ABSTRACT:
A device for grounding a coaxial cable to a ship's hull or bulkhead having n 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.degree. 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.
