The channel selection signal is flagged to retrieve satellite parameters corresponding to the selected channel from a pre-stored satellite channel table which provides a correlation among the channels, the bands and the satellite coordinates. Then, according to the retrieved satellite parameters, an antenna control signal and thus a drive signal are generated orderly to drive the antenna to direct at the satellite responsible to the selected channel.

Abstract: The present invention discloses a satellite disc antenna and its structure for displaying an integrally formed trademark through hollow holes by a visual contrast effect. The antenna is formed by punching holes on a metal plate to constitute a holed plate with densely distributed hollow holes, while maintaining the disc surface of a desired trademark pattern free of holes, so that the integrally formed trademark pattern can be shown clearly on the disc surface by the visual contrast effect. The satellite disc antenna can be manufactured synchronously without requiring any printing or coating. The invention can reduce the influence of climate changes and prevent the trademark pattern from being peeled off easily. Further, the hollow holes can be used for reducing the wind resistance, enhancing the durability of the antenna and maintaining the reliability of receiving signals.

Moreover, the structure in accordance with the invention can withstand the inertia toque created by the strong wind force acting on the receiving dished plate.
