1. An antenna roof mount for a vehicle having a roof portion with a thin integral layer of dielectric material existing on the roof portion which serves as the decorative coating of the roof portion, said roof mount comprising:

  • a base plate for transverse positioning across said roof portion;

    said base plate being nonconductively attached to said roof portion;

    housing means coupled to said base plate, said base plate being substantially wider than said housing means, at least in the area of coupling between said housing means and said base plate, and of sufficient size to provide capacitive coupling between an antenna and the vehicle to provide a suitable ground connection for the antenna;

    antenna means supported by and extending from said housing means;

    a coaxial cable having an outer conductor connected to said housing means and an inner conductor connected to said antenna; and

    mounting means for securing said base plate directly onto said integral dielectric material on the roof portion without any further dielectric material therebetween whereby the integral dielectric material also serves as coupling means for capacatively coupling said base plate to said roof portion.
