The antenna has first and second antenna elements, with a third antenna element comprising a socket connected to the second element. There is also a connection arrangement. The first antenna element is arranged to assume at least a first and a second operative position. At one position, the element capacitively connects to the third antennal element, constituting an antenna for a certain frequency band, in which the second antenna element acts as a blocking element. The first element may be a helical, meander or whip antenna. |
