ABSTRACT:
A radio antenna device having a gain compensating circuit and an antenna wire rigidly secured to the rear window of a motor vehicle, coupled with a moisture preventive heat wire. The antenna wire is secured to the rear window of the motor vehicle so as to reduce the noise in the received radio waves, which results from electrical noise from the vehicle engine, electric generator and electric motor. The rear window also serves as a convenient antenna space. A gain compensating circuit is provided for compensating for the reduction in the level of the received radio wave, which reduction is caused by the shielding action of the moisture preventive heat wire secured to the rear window and the portion of the body of the vehicle, which extends along the periphery of a rear window.
