A device for grounding a coaxial cable to a ships 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 ships hull and overlying the opening, such that the split forms substantially 360 deg of coupling between the bared shield and the ships hull. This configuration increases the area and effectiveness of electrical contact between the bared shield and the ships 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.
