Abstract:
A shield current trap for use with a shielded cable having an outer shield surrounding at least one inner conductor, the shield current trap comprising:a) a first trap element having a first inner conductive channel joined at respective first and second axial ends by a first and second radial conductor to first and second ends of a first outer conductive shell to form a first resonant loop; b) a second trap element having second inner conductive channel joined at respective first and second axial ends by a third and fourth radial conductor to first and second axial ends of a second outer conductive shell to form a second resonant loop; whereby the first and second inner conductive channels may be assembled in opposition to enclose the axially extending shielded cable; and c) a clamp assembly for controlling the separation of the first and second trap elements whereby coupling between the first and second resonant loops may be controlled to adjust a frequency at which the first and second conductive loops are resonant.
