1. Electrical equipment, comprising:
an internal antenna;
an external connector to which an external antenna is connectable;
a first radio module;
a second radio module;
an RF link enabling the second radio module to be connected to the external connector;
a detector device arranged, when a test signal is transmitted over the external connector via the RF link, to produce a detection signal representative of whether or not the external antenna is connected to the external connector;
control means arranged to control the second radio module so that it generates and transmits the test signal via the RF link, to acquire the detection signal, and depending on the detection signal, to connect the first radio module to the external connector if the external antenna is connected to the external connector, or else to connect the first radio module to the internal antenna if the external antenna is not connected to the external connector.
