Abstract

An inground housing is insertable in at least one joint of a drill string extending from a drill rig. The inground housing supports an electronics assembly for processing a data signal relating to the inground operation and a signal coupling arrangement for transferring the data signal between the electronics assembly and the drill rig by electromagnetically coupling the data signal between the signal coupling arrangement and the drill string such that the data signal is electrically conducted as an electrical data signal along at least a portion of the drill string that extends from the inground housing. In another feature, a current transformer is resiliently supported to isolate the current transformer from mechanical shock and vibration that is produced by an inground operation that is performed using the drill string. In another feature, a drill string repeater is described.
