Abstract
A telemetry assembly for inclusion in a drill string or the like comprises a collar (10) carrying a coil (22) wound on a ferromagnetic toroid (21). These are positioned in a recess in the collar which is filled with a dielectric material (20). The coil (22) is surrounded by a ferromagnetic sheath (30)
