  • Frequency tuned antenna assembly
    Patent number: 4739516
    Abstract: A fixed length antenna rod projects from a housing enclosing a pre-amplifier circuit connecting it to the front end of a FM receiver. The antenna rod is mounted at an optimum signal reception attitude by the flange of a bracket to which the housing is secured and through which an output cable terminal of the pre-amplifier circuit extends. The preamplifier circuit is adjustably tuned to favor a specific frequency for subcarrier transmission and attenuated in signal gain to match antenna signal pick-up level.
