    Abstract: An antenna (10) is described comprising a generally elongate, magnetically permeable core (12) having a major axis, an insulating substrate (20) being affixed to the core (12) along an axis parallel to the major axis, and having at least a pair of opposed spaced conductive runners (21) positioned along the substrate normal to said major axis. A plurality of charge storage devices (capacitors) (16) are secured between the pair of opposed spaced conductive runners (21). An electrically conductive split sleeve (14) is positioned surrounding the core (12), and has first and second edge portions (26) in electrical connection with the pair of opposed spaced conductive runners (21) opposite said charge storage devices (16). Arrangements for mechanically mounting the antenna (10) are provided which are integral to the antenna (10). The mechanical mounting arrangements are separate from the arrangements provided for electrically connecting the antenna 10 to the receiver. The mechanical mount includes grooves (28) to receive a pcb, projections (40) of the sleeve (14), interconnecting posts, tapered core projection interegaging with a pcb, or snap-fit latches between the core and a housing. Electrical connections to a pcb comprise sleeve projections (18), conductive tracks on the substrate (20) or parts upstanding from the substrate.
