A roof mount for coupling an antenna to the roof of a vehicle and simultaneously providing a capacitive coupling for grounding the antenna to the vehicle frame. The antenna is supported by a housing which is connected to a base plate which in turn fits transversely across the roof of the vehicle. The ends of the base plate are clamped onto the edges of the roof to be firmly held in place. The base plate is separated from the metallic roof either by a vinyl roof top or by a layer of paint, depending upon the type of vehicle. The base plate is then capacitively coupled to the vehicle for providing a ground to the antenna. The roof mount can accommodate various sized antennas and various types of feed through cables depending upon the equipment to which the antenna is connected.
