The present invention relates to a hearing instrument which comprises: (a) a housing; (b) an RF
receiver; (c) plurality of conductive elements, each conductive element has the form of a plate, is positioned on said housing so it provides
coupling with the device wearer's
skin while the instrument is in use, thereby forming an
antenna element together with the wearer's body; (d) a switch for each conductive element, for connecting or disconnecting the respective
antenna element from the
receiver; (e) a controller for periodically initiating a testing cycle wherein during said cycle: (e.1) the controller sequentially scans said switches by closing each time another switch, thereby to connect each time a respective
antenna element to said
receiver; (e.2) each time said antenna switching is performed and a specific antenna element is connected to the receiver, the controller samples and stores a respective quality indication
signal which is indicative of the quality of the received
signal by said receiver via said respective antenna; (e.3) the controller inspects all said stored indications, determines from all said stored indications the one that relates to a best quality
signal, and connects the antenna element which corresponds to said best quality signal to said receiver for a
time duration which is substantially longer than the duration of said testing cycle, until performance of a next testing cycle.
