Antenna is namely the “Cauldron” we always called, which is parabolic object made of metal. It is used to reflect the satellite signal into feed and LNB at focus point. Generally speaking, the bigger the antenna aperture is, the stronger the program signal is and the higher the receiving quality is. But in view of cost and installation, customers ask for smaller antenna aperture. For example, inAsia3S, domestic digital programs at C-band just need our1.5mor smaller antenna to get high-quality images and audio. While for programs at Ku-band, DBS like Korean Satellite just need0.6meven0.35mour offset antenna. But to receive the same program, the same aperture antenna of other brands can’t reach this because of lower quality, accuracy and gain. Therefore, you should choose products with reliable quality, excellent craft and high accuracy like Antesky antennas. One super quality antenna requires high accuracy, corrosion resistance of surface, strong wind loading, high efficiency, high gain and durable service.
Among many fanciers and customers, satellite antennas can be divided into prime focus antenna and offset antenna. Prime focus antenna is namely the “Cauldron” we always called to receive C-band programs; while offset antenna is also called “Konabe” to receive Ku-band antenna. C-band antennas have1.35m,1.5m,1.8m,2.1m,2.4metc. In northeast ofChina, these antennas can receive all the civil channels and also international famous channels such as Phoenix TV, CNN, BBC, NHK and so on. The regular aperture of Ku-band antennas are0.35m,0.45m,0.6m,0.75m,0.8m,0.9m,1.0m,1.2m,1.5metc. which can satisfy the requirement of cable television and “Every Village Project.” Different from prime focus antenna, offset antenna has elliptic appearance, shallower surface radian and lower elevation.
