The invention concerns the electronic display of data such as prices along gondolas displaying products on premises (6) such as a retail shop, comprising a plurality of sending antennae (a1, a2,....., an) in a current loop forming at least wires (b1, b2,....., bn) extending horizontally and arranged such that the whole zone in line with the first wire of a first antenna is covered by a range zone of a second wire. Automatic switch means (11, 12) provide for applying successively on the various sending antennae each of the streams of signals, so that every display module receives the emitted waves and there is no shadow area in the premises (6).
