Due to the greater height 100 of the non-powered second radiator element 10 whose resonant frequency with respect to the resonant frequency of the first radiating element 5 is slightly detuned. This results in a phase shift of the current on the second radiator element 10 with respect to the fed first radiator element 5 and there is a directivity.

If the quality of the connection falls below a first correspondingly predetermined value, for example because the radio 1 with the antenna arrangement 5, 10 is so awkwardly positioned that the antenna arrangement 5, 10 radiates in the wrong direction for the current connection, then the controller 85 controls the PIN diode 35 low level, so that the PIN diode 35 goes into a blocking state and the second radiator element 10 is connected at its base 150 high impedance to the reference potential 80. In this case, the antenna arrangement 5, 10 acts as omnidirectional antenna with omnidirectional radiation characteristic, so that the emission power in accordance with FIG. 6 is about the same size for all directions and according to FIG. 6 a directional diagram with omnidirectional radiation pattern 20 results.
