PURPOSE:To perform the channel selection of a desired satellite broadcast with a single operation and to improve operability, by presetting the combination of a satellite and a channel in advance, and selecting the channel corresponding to a prescribed satellite broadcast at the time of receiving it. CONSTITUTION:Firstly, the desired combination of the satellite and the channel corresponding to plural satellite broadcasts are preset on the memory 3a of a control part 3 by a presetter 10. At this time, for example, when it is desired to receive the satellite broadcast of the channel 5 of the satellite 3, for example, the switch 2 of a channel selection switch 11 corresponding to an address 2 is operated. Thereby, the control part 3 reads out the data of the satellite 3 and the channel 5 from the memory 3a designated by the address 2, and outputs corresponding data of an azimuth and an elevation angle, etc., to an antenna position controller 4, and also, outputs the signal of the channel 5 to a tuner 6 via a PLL pre-scaler 5. The controller 4 controls a parabolic antenna, and the tuner 6 performs the channel selection of the channel 5 out of channels received from the satellite station 3 with an antenna.
