Abstract
This invention discloses a novel design for receiving electromagnetic signals broadcasted from at least two of satellite clusters and collected by a single dish antenna. At least two signal feeds are used to feed the signals to a processing circuit. The processing circuit performs signal selection, amplification, and frequency conversion. Corrective lens are used to ensure uniform wavefront of the electromagnetic signals received by the signal feeds located farther away from the focal point of the dish antenna. A convenient adjustment device is provided for adjustment of the relative positions of the signals feeds to the dish antenna.
