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).
An antenna device for a piece of equipment for transmitting and/or receiving radio signals, said antenna device comprising a first extendable antenna which is movable between an extended position where the first extendable antenna is coupled to circuitry of the piece of equipment and a retracted position where the first extendable antenna is essentially not coupled to said circuitry, said extendable antenna having a lower portion equipped with first holding means for cooperating with second holding means arranged on a guide means for holding the extendable antenna such that the extendable antenna is releasably locked in the extended position, wherein the extendable antenna is releasably locked by magnetic attraction between the first and second holding means, said first and second holding means comprising mutually magnetically attractive elements.
An antenna device for a piece of equipment for transmitting and/or receiving radio signals, said antenna device comprising a first extendable antenna which is movable between an extended position where the first extendable antenna is coupled to the circuitry of the piece of equipment and a retracted position where the first extendable antenna is essentially not coupled to said circuitry, said extendable antenna having a lower portion equipped with first holding means for cooperating with second holding means arranged on a guide means for holding the extendable antenna such that the extendable antenna is releasably locked in the extended position by magnetic attraction between the first and second holding means, said first and second holding means comprising mutually magnetically attractive elements and wherein at least one of the first and the second holding means includes a magnet.
A piece of equipment for transmitting and/or receiving radio signals including an antenna device comprising an extendable antenna which is movable between an extended position where the extendable antenna is coupled to the circuitry of the piece of equipment and a retracted position where the extendable antenna is essentially not coupled to said circuitry, said extendable antenna having a lower portion equipped with first holding means for cooperating with second holding means arranged on a guide means for holding the extendable antenna such that the extendable antenna is releasably locked in the extended position by magnetic attraction between the first and second holding means, said first and second holding means comprising mutually magnetically attractive elements and wherein at least one of the first and the second holding means includes a magnet.
