摘要： The invention relates to a ferrite antenna, comprising at least one winding (4), which is arranged around a core (2) consisting of ferrite material. A second core (3), consisting of ferrite material and running coaxially to the first core (2), is allocated to the first core (2), which carries the winding (4) and is rigidly fixed in the coil carrier (1). Said second core, which can be displaced in an axial direction in the same coil carrier (1), is positioned in such a way that the opposing front faces of the two cores are placed at a predetermined distance from one another. Said distance can be altered by displacing the second core (3) in an axial direction in order to tune the antenna. After tuning, the second core (3) can be fixed in or on the coil carrier (1).
