ABSTRACT:
An FM wave antenna including a coaxial cable, a parallel conductor which are provided parallel to a metal conductor such as a vehicle body and an amplifier provided between the coaxial cable and the parallel conductor. The coaxial cable is made up of a central core and inductive outer sheath and one end of the inductive outer sheath is connected to the metal conductor, and one end of the parallel conductor is also connected to the metal conductor. The amplifier amplifies signals from the parallel conductor and inductive outer sheath of the coaxial cable and outputs amplified signals to the central core of the coaxial cable.
