A plurality of high-frequency pickup are provided on the vehicle body at positions spaced from each other and the pickup which has the best reception at a given time is automatically selected by a diversity circuit. Each of the high-frequency pickups is provided in proximity of a marginal edge portion of the vehicle body in order to pick up the high-frequency surface currents which are induced by the broadcast waves and flow concentratedly on the marginal edge portions of the vehicle body. The high-frequency pickup includes a loop antenna or an electrostatic electrode which is disposed in proximity to a marginal edge portion of the vehicle body. The position for fixing the pickup is selected from among the vicinity of a retainer on which an edge molding for a window frame is mounted, a window pillar, a truck lid and an engine hood.
