The second waveguide tube includes the third tube part and the fourth tube part; one end of the third tube part is connected to the main body; its length direction is parallel to the main body plane; one end of the fourth tube part is connected to the third; and its length direction is normal to the main body plane.

Description

technical field [0001] The present invention relates to a satellite signal down-converter, in particular to a satellite signal down-converter for receiving signals sent by different satellites. Background technique [0002] refer to figure 1 , which shows a known satellite antenna receiving device, which includes a dish antenna 110 and a satellite signal downconverter 120 . The satellite signal downconverter has waveguides 121 , 122 and 123 to receive satellite signals transmitted from satellite groups (satellites 131 , 132 and 133 ). [0003] Referring to Fig. v, it shows the signal receiving situation of the known satellite antenna receiving device, the satellite signal sent by the satellite 131 is reflected by the dish antenna 110 (reflecting surface) and received by the waveguide 121 . The satellite signal sent by the satellite 132 is reflected by the dish antenna 110 and received by the waveguide 122 . The satellite signal sent by the satellite 133 is reflected by th...
