"Do you know why the satellite pot is disabled?"
Some people may think that it is because the satellite pot function is so poor, but it is not.
The reason why the satellite pot was banned is related to a ban proposed by the mainland, which is to maintain the mainland's national security and social stability.
So what is the reason for this ban?
And what is the function of the satellite pot?
So what can it see for a satellite pot?
What are the dangers?
First, the function of the satellite pot.
A satellite pot is generally a device used to receive satellite signals.
As we all know, there are many satellites on the continent, and these satellites are also orbiting the earth, and the satellites also orbit each other.
What the satellite pot can receive is the signal emitted by these geosynchronous satellites.
We can receive a lot of foreign program signals, we can also receive some weather forecast signals, and we can also receive some news and information from them.
And these satellite pots can also receive some entertainment programs and so on, which can meet people's entertainment needs.
For satellite signals, a special receiving device is required to receive them.
And this device is a satellite pot.
As we all know, satellites operate at a very high speed, and the signals emitted by geosynchronous satellites are also transmitted in the form of radio waves.
So how is it possible for a satellite pot to receive it over such a long distance?
This has to be analyzed from the structure of the satellite pot.
The shape of the satellite pot is a large arc of metal, and this metal arc is used to reflect the satellite.
When the signals emitted by the satellite reach the satellite pot, they will be reflected by the metal arc first, and then reflect these signals to the center of the satellite pot, which has a high-frequency head.
The high-frequency head captures the reflected signals, converts them into electrical signals, and transmits them to the satellite receiver.
The satellite receiver will also do some processing of these electrical signals, and then send these signals to the TV, through which the signals are decoded.
And then we'll see some of the shows on TV.
It is precisely because the satellite pot has such a powerful function that it is also widely used in many places.
Second, the hazards of satellite pots.
Although the satellite pot is very functional, it also has some disadvantages of its own, and these shortcomings are also one of the reasons why the satellite pot is disabled.
The first is that the satellite pot is susceptible to the influence of the weather, as long as it is in a rainy day, a windy day, a thunderstorm, etc., then it is possible to have some impact on the satellite pot, and may even cause some failures.
And when these weather passes, when we watch TV, there will be some blurred screens, or the signal is unstable, and even the satellite pot will not work.
In addition, the signal of the satellite pot is still transmitted through electromagnetic waves, and we all know that electromagnetic waves have a certain amount of radiation, which will cause some infertility diseases for some people who use the satellite pot for a long time.
These diseases may have an impact on their next generation, and may also cause their children to develop some congenital diseases.
Therefore, satellite pots are also harmful.
In addition, there are some channels and information received by the satellite pot, which may not be healthy.
Therefore, when the state introduced a policy, some people installed satellite pots at home to receive some unhealthy channels and information from abroad.
For some minors, this information may have a certain impact on them, and even have some bad effects on them, so the state has issued a ban on people installing satellite pots in their homes.
3. Why is the installation of "satellite pots" prohibited?
So when was this ban issued?
The ban was issued in 2011 by the State Administration of Radio, Film and Television and the Ministry of Public Security.
This ban was issued to safeguard the mainland's national security and social stability.
At that time, it was a move by foreign forces, so that the mainland's TV programs could be better disseminated, and the mainland's culture could be better spread to all corners of the world.
In addition, in order to better inherit the culture of the mainland, the state has issued this ban on people from installing satellite pots at home, and this ban is also to maintain the national security and social stability of the mainland.
In addition, in order to eliminate some potential safety hazards, and also to let people see healthier channels and information, the state has imposed regulations prohibiting the installation of satellite pots.
III. Conclusion
With the continuous development of science and technology in mainland China, digital TV is also constantly popularized, and digital TV also has many advantages.
It is transmitted in digital form, which can not only better save resources, but also better avoid some interference, in addition, digital TV can better receive some program signals, and can also watch clearer pictures.
The satellite pot is also slowly being replaced by digital TV, so I also hope that when you use some technology products, you can abide by some national regulations and don't bring some trouble to yourself and others.
