Abstract

A diversity controller (5) for a video receiver (10) includes a beamforming network (3) that combines received video signals at two or more antennae to provide a plurality of antennae combination signals. A high speed RF switch (4) is responsive to a received signal quality measure for asynchronously coupling one of the plurality of antennae combination signals to the video receiver.
