Abstract
An antenna system for receiving horizontal and vertical components of a transmitted horizontally polarized digital RF signal. The system includes a vertical antenna for primarily receiving vertical components of the RF signal and a horizontal antenna primarily for receiving the horizontal components of the RF signal. An adjustable time delay changer is provided for adjusting any time delay of one of the components. A combiner combines the components to obtain therefrom a combined RF signal for application to an RF utilization means. The combined RF signal is a digital signal exhibiting a bit error rate dependent upon the value of the vertical component. An RF decoder decodes the bit error rate and provides a bit error rate signal having a value that varies as a function of the value of the bit error rate. An adaptive controller responds to the bit error rate signal and adjusts the time delay changer in a direction to decrease the value of said bit error rate signal.
