Abstract
Abstract An antenna system is provided for receiving horizontal and vertical components of a transmitted RF signal and for minimizing the magnitude of one of the components prior to application to an RF utilization means, such as a TV receiver. The system includes a vertical antenna for primarily receiving the vertical components of the RF signal. A horizontal antenna serves to primarily receive the horizontal components of the RF signal. An adjustable time delay serves to adjust the time delay between the vertical and horizontal components. An adjustable phase adjuster serves to adjust the phase between the vertical and horizontal components. A combiner combines the adjusted horizontal and vertical components to obtain therefrom a combined RF signal for application to the RF utilization means.
