  • Whip antenna assembly and method of manufacture
    Patent number: 4086596
    Abstract: There is disclosed an antenna including an accurately formed whip member and an accurately formed loading coil one end of which is connected to one end of the whip member and the other end of which is connected to a single connector. The length of the whip member and its diameter and any associated metallic connector are selected to give a predeterminedly accurate capacitive value. The loading coil has a predeterminedly accurate inductive value such that the loading coil and whip member have a net accurate inductive value which is connected to a predeterminedly accurate capacitor for matching the impedance of the antenna to the conductor, coaxial cable for example, from the transmitter. The capacitor, a single stub connector, the end of the coaxial cable and the necessary connections are epoxy encapsulated in a base housing.The connector at the end of the loading coil is attached to the single stub connector in the base to provide the only connection necessary for the antenna to become operative.
