Who knows the working principle of the satellite TV ground receiver?
A new type of satellite receiving antenna to achieve "no pan" reception"!Based on the above definition of the satellite "pan", we can answer with certainty that "no pot reception" can be achieved. Because the satellite "pot" (i.e. parabolic antenna) is just a member of the big family of the satellite receiving antenna, receiving equipment it is using the principle of reflection waves is made; in addition using the new wave of reflection, refraction principle of antenna made of receiving satellite signals, this is what we call "receiving pot".At present, in the "receiving no pot", mainly used a horn antenna, planar antenna and lens antenna of the three satellite receiving antenna; the horn antenna and planar antenna is the use of direct wave principle, and the lens antenna is to use the principle of refraction waves.
What is the "pot" in satellite reception?In satellite receiving the "pot" is a vivid saying, because often using parabolic satellite TV receiving antenna, and reflective paraboloid antenna surface and we use in daily life an appearance similar, so people called parabolic antenna called a satellite "pot" or "pot", referred to as "pan".A parabolic antenna are fed antenna and offset antenna two, reflecting surface area are fed antenna is relatively large, so called "big pot"; offset antenna reflection area of relatively small, known as the "pot" or "small ears".Some satellite enthusiasts use a large iron pot made of pig iron material in rural areas to receive KU band signals. Ha ha, this is the real pot!
Uncover for you the secret of satellite TV no pot receptionA new type of satellite receiving antennaAt present, in China, individuals are generally not allowed to install or use satellite ground receiving facilities because they are still limited by policies. For some unscrupulous businessmen to make satellite TV "Pan received" product advertising, claiming that the use of this product, without receiving TV set up outdoor pot "can receive satellite TV signal, very attractive.About the so-called "no satellite signal receiving pan", such as some businesses propaganda "compatible technology and global positioning system GPS and SOS automatic search system uses digital AOMM double magnetic high-frequency international advanced production, high frequency, no pot receiving, anti jamming equipment, replace the pot surface receiving system!" Some of these readers are heard and not like, but listen to the technical terms said if elected, I do not know whether this kind of satellite receiving equipment. In our previous magazine, also not in-depth introduction, we will take you to the unveiling of the satellite TV signal "receiving no pot", and also introduce the new technology of satellite receiving antenna.
