  • Abstract
    In recent evaluations of large parabolic reflector antennas, engineers have investigated the antenna performance at several frequencies. In this paper it is shown that the efficiency at any frequency can be estimated from a measured efficiency at another frequency and a carefully calculated design efficiency. In practice, an efficiency measurement at some frequency usually serves to determine the efficiency at all lower frequencies.
