New type description: [Technical field to which the new type belongs] This creation is related to satellite signal receivers, especially a type of satellite signal receiver that can be connected to multiple groups. 5 [Prior art] When receiving satellite signals, a dish antenna must be pointed at the position of a sync satellite in order for the antenna to receive the satellite signals transmitted by the sync satellite; because satellite signals are being transmitted from the sync satellite In the process of reaching the antenna, the satellite signal will be affected by the distance and the air. Therefore, the satellite signal collected by the antenna is usually transmitted to a satellite signal receiving state, and the high-frequency satellite is received by the shouting satellite signal receiver. After the signal is down-converted and amplified to the intermediate frequency, the satellite signal is transmitted to a set-top box located indoors through a coaxial cable. If you want to receive the satellite signal transmitted by two synchronized satellites, you need to use two disks. Type antenna and satellite signal receiver, respectively, after receiving satellite 15 satellite signals, each satellite signal receiver is then connected to a signal selector with a coaxial cable and a set-top box connected to the signal selector. The signal selector chooses to receive satellite signals transmitted by any geostationary satellite. However, since the signal selector and the set-top box are usually located in the room 20 The satellite signal receiver and the dish antenna are located outdoors. Therefore, the length of the coaxial cable connected to each satellite signal receiver and signal selector is longer. At the same time, when each component is set up, each coaxial must be installed separately. Cables and signal selectors can receive satellite signals smoothly, making installation methods more complicated and costly. 4 M284141 [New content] Therefore, the main purpose of this creation is to provide a satellite signal receiving income, which can be connected to multiple groups to make the installation methods between the various components easier, thereby reducing costs.
