ABSTRACT:
An installation for an antenna, particularly advantageous for use in connection with a transceiver in a mobile vehicle, comprising first and second means, each of which includes electrically conductive material, adapted to be fixed, without need for mechanical fasteners, in facing relation and in respective connection with inner and outer surfaces of a portion of a structure capable of providing a dielectric therebetween, the one of said means connecting to said outer surface providing for mount of an antenna in connection with the electrically conductive material thereof which forms one plate of a capacitor, the opposite plate of which is provided by the electrically conductive material of the other of said means which connects to said inner surface, and the said means which connects to said inner surface including means for coupling of the electrically conductive material thereof to conductive means in connection with said transceiver. In preferred embodiment and application, the means which connects to said inner surface and includes said other plate of said capacitor is so comprised as to provide for fine tuning of the antenna system of which it forms a part.
