1. A method for directing an antenna to receive an advanced television signal, comprising the steps of:
- measuring the strength of the signal as a function of the azimuth angle of the antenna;
measuring the flatness of the signal as a function of the azimuth angle of the antenna;
rotating the antenna to maximize the flatness of the signal while maintaining the strength of the signal above a minimum threshold.

Abstract
An antenna is directed to optimally receive an advanced television signal. First, the strength of the signal is measured as a function of the azimuth angle of the antenna, and second the flatness of the signal is measured as a function of the azimuth angle of the antenna. The antenna is then rotated to maximize the flatness of the signal while maintaining the strength of the signal above a minimum threshold.
