A thick ground line (8) is serigraphed onto the rear window (2) and a two-wire cable (11, 12) joins the aerial FM2 to an electronic housing (9). On a quarter panel window of the vehicle, the aerial is serigraphed in the form of an F-shape of the servitude antenna and joined by a two-wire cable (19, 20) to an electronic housing (9).
