In order to minimise switching losses in aerial switches for wireless aerial diversity telecommunications devices with two aerials, e.g. a base station of a DECT wireless telephone, there is an electronic switching component (SE1, ..., SE4) in the form, for example, of a PIN or switching diode, in a first signal path (SW1) from a transmitter (TR) to a first transmission/reception aerial (A1), a second signal path (SW2) from the transmitter (TR) to a second transmission/reception aerial (A2), a third signal path (SW3) from a receiver (RE) to the first transmission/reception aerial (A1) and a fourth signal path (SW4) from the receiver (RE) to the second transmission/reception aerial (A2). The switching components (SE1, ..., SE4) thus form a ring circuit with the signal paths (SW1, ..., SW4).
