A method for manufacturing an antenna unit, including a resilient, metallic core (10), which is in the form of a wire, and an injected, insulating jacket at least partially enclosing the core, wherein use is made of an injection moulding tool, which is split in a parting plane (D), containing the longitudinal, central axis of the core. The insulating jacket is injection moulded in two steps. The core is in a first step provided with a first jacket portion (15), while the remaining part of the core is supported in a first mould cavity portion (11B), which is adapted to the shape of the core. At least a part of the injection moulding tool and the core with the injected first jacket portion are displaced in relation to each other. In a second step, the still bare part of the core is provided with a second jacket portion, supplementary to the first-mentioned jacket portion, while the core (10) with the injected first jacket portion (15) is supported inside a second mould cavity portion (19), which is adapted to the shape of the first jacket portion. |
