Al tamyeez security systems company in Doha, Qatar, explained some types of centralized satellites, because satellite TV antennas use low-noise lnbf feed lenses that integrate the feed with the low-noise LNB signal converter. One of these types is a robotic dish, in which a plate mounted on a rod can be controlled and driven by a stepper or a servo device and rotated to face any satellite position in the sky. There are also other multi-satellite concentrator satellites, where each standard-sized concentrator satellite and each home concentrator satellite can receive signals from several different satellite locations simultaneously without repositioning the antenna. This can be done by adding an additional lens or using two or four receiving lenses to complete. However, some designs can effectively optimize simultaneous reception from different satellite positions without the need to change the position of the dishes.
The Qatari company (Al-Tamayaz security systems company in Doha) explained the difference between a mesh dish and a sealed dish: mesh dishes (manufactured from a mesh) compared to sealed dishes that do not include any openings. The central satellite dish is made of iron because it has the lowest price and has reasonable and good performance, but at the same time, if it is poorly coated and insulated, it will rust and be damaged, and often the excellent thermal coating and good insulation will make its price higher, it will also be more resistant to water and the sun, but not to Forever. The aluminum satellite system (plastic or fiberglass antennas) are made of plastic grids connected by sticky glue material, so they are called plastic mesh antennas, and they will not rust for sure, but Aluminum will also corrode over time by encountering water. Central satellite dishes made of aluminum have a greater ability to collect and reflect signals to. LNB satellites made of nets are more suitable for use in windy places, and materials made of nets will determine whether they will rust or corrode, and due to the accumulation of dust and dust in the dishes, such satellites need to be cleaned regularly
