Satellite antenna is often said that the small pot and pan, is a metal parabolic, in charge of the satellite signal reflection to the focus in feed and high frequency in the head.Satellite antenna is the role of the weak signal collected by satellite, and as much as possible to remove noise.Most of the antenna is usually a parabolic shape, there are also some more focus antenna is made up by spherical and parabolic. Satellite signals through a parabolic antenna the focus of the reflection on it.In the satellite antenna installation business in Qingdao area,Word of mouth reputation and professional best first morning star technology company (the company free consultation telephone: 15610564444),Can provide a variety of satellite TV installation, such as 122 degree DISH HD foreign HD, sky digital 138 degrees in Taiwan, Hongkong cable, Hongkong Yihua live, 116 degrees South Korea sky life direct broadcast satellite, 113 degrees of Han Chinese broadcast, satellite, Japan, the Russian satellite, USA satellites.
Qingdao area in general, the antenna aperture is more big, the stronger the signal receiving program, the higher the quality,But considering the cost, installation and other factors, the user requirements of the antenna aperture smaller is better. Such as the Zhongwei 3S C band antenna to Asia on the domestic digital program only 1.2M or less to receive high quality images and sound,And Ku band show, like Korean direct broadcast satellite only 0.6 M and 0.35 M central defender can feed antenna.TV box receives the same program, some different brands, antenna of the same size but was unable to do, the reason is that the quality and precision of the antenna is not high, resulting in low efficiency, low gain, so when the choice of satellite antenna must choose reliable quality, sophisticated technology, high precision of the brand-name manufacturers of products.A high precision, high-quality satellite antenna requirements of surface corrosion resistance, wind resistance ability, high efficiency, high gain, durable.
Satellite antenna is fed and offset can be divided into two types:Positive feedback is what we call the cauldron, receiving C band shows. Partial feed is also called small pot, receive Ku programs.
C band antenna has 1.35, 1.5, 1.8, 2.1, 2.4M and various specifications,In Qingdao area all these specifications can completely satisfy the receiving domestic channels and phoenix satellite TV channel, CNN, BBC, NHK and other international famous needs. Americas South Korea, and other
Qingdao Star Technology Satellite TV installation company operating the following types of antenna:
1.The center focus of satellite antenna.
2.FRP-Forming one satellite antenna.
3.Stamping iron plate antenna
4.The polar axis of chain type antenna
5.Single push rod polar axis
6.Elevation azimuth drive antenna
7.Satellite automatic tracking antenna
8.Mobile satellite antenna
9.Plate satellite antenna
Satellite TV receiving system is composed of: composition, feed parabolic antenna, satellite receiver, tuner. In Qingdao to install the paraboloid antenna, according to the general structure diagram of manufacturers to provide installation.Antenna structure of various manufacturers are similar basically the same.Reflection plate antenna structure with the integral forming and split two (reflecting board above 2M is essentially split), upright tripod and three foot two main tripod (column tripod is common), individual one point eight meters below the horizontal tripod tripod,The following is the basic installation steps: horizontal tripod mounted on the base of ready, correction levels, then sturdy tripod wire and welding fixed (horizontal tripod must first adjust the azimuth before fixing the tripod).Mount Range tray and elevation angle adjusting screw.In order to strengthen the reflection plate bracket and a reflection board is arranged on the reflecting plate tray, the reflecting plate and the reflecting plate is fixed connected slightly can temporarily not fastening, all installed, adjust the smooth surface and then all screw firm,Bring attention is split reflecting plate and some manufacturers are no sequence can be assembled, but some three flap is the installation of installation of feed supporting rod, the three valve shall be installed inside three minutes, otherwise not coincident impact signal reflection focus gain asymmetric source and the antenna feed bracket is arranged on the even after not receiving to signal.
