Abstract
Abstract An antenna device for a piece of equipment for transmitting and/or receiving radio signals, wherein the antenna device comprises a first extendable antenna (2), which is movable between an extended position, where it is coupled to the circuitry of the piece of equipment and a retracted position where it is not coupled to the circuitry, the extendable antenna (2) on its lower portion having first holding device (10) cooperating with a second holding device (9) arranged on a guide (5) for the first antenna such that the first antenna is releasably locked in the extended position. According to the invention the first antenna (2) is releasably locked by the first and second holding devices comprising mutually magnetically attractive elements (9,10).
