Why do TV satellite dishes have to be facing southwest? Are there any other risks towards it?

In Chinese mainland, satellites are arranged in east longitude, that is, from west to east. Specifically, there are satellites from 49° east longitude to 180° east longitude to east south. There are currently suitable satellite programmes available in both the west and east of China.

Then it depends on the exact location of your location (can ** "Star Finder" software), watch the free can be according to the "enthusiastic netizens" suggested to receive the east longitude of the Asian 3S satellite, you need an ordinary receiver and an antenna with a diameter of at least meters to watch (the whole set of equipment is about 200 yuan). Otherwise, you can only watch encrypted programs, you can buy a "DM500 receiver" (network support is required) or a "digital low-end live broadcast machine" (no network support is required, you can receive Phoenix but not NHK) and a 45-60cm caliber antenna to receive the program of the Asia-Pacific 5 satellite KU wave at 138 degrees east longitude (the whole set of equipment is about 500 yuan).

If you buy a DM500, you can share and receive the 134-degree Asia-Pacific 6 KU band in Tokyo, where there are many good TV programs, including Phoenix TV and NHK

The satellite is in the southwest direction. There are no satellites in other directions... You can buy some threads. Put it on the roof.

Asia No. 3 has Phoenix Satellite TV, which is free, and I have a pot of Samsung!

The communication satellites are all geosynchronous satellites, all over the equator, and China is in the northern hemisphere, so the satellite antennas are aimed at the south. Depending on the longitude of the satellite and the longitude of the receiving location, it will face southeast or southwest. Generally, there is a balcony on the south side, and there is no shelter in front of it.

For specific receiving plans, you can post on the Star-Seeking Technology Exchange Bar.

Because the satellite is over the equator, the right direction should be southward and east-west, and the right satellite will have different angles! The two stations you watched were broadcast for free on Asia 3S! This satellite could also be west-south-west for you!

The satellite is in our southwest, and the antenna should be facing the satellite. If it's not too far from the roof, put it on the roof. Neighbors?

Look at the programs you search for, the satellites aimed at are different, and the direction is different.

The pot is aligned in the direction of the satellite, which is synchronized with the Earth.

Because the satellite is in that direction.

By the way, the plan of the year lies in the spring.

No, the satellite antenna pot receives the signal sent by the satellite, because the satellite is very high, and the signal is sent to the earth through radio radiation, and it will cover thousands of kilometers if it is dispersed to the ground, for thousands of kilometers, your satellite antenna is just a negligible point, it doesn't matter which way it is facing, hehe.

In the geosynchronous orbit of the satellite in the geosynchronous orbit of 10,000 kilometers above the equator, the satellite antenna must be aligned with the satellite in order to receive the satellite signal to the maximum extent, otherwise the gain of the antenna must be increased, of course, the gain of the noise signal will be increased at the same time, which is not conducive to reception. You can refer to the antennas of other satellite dish users, look at the elevation angle, and compare it to know that your home installation is not affected, if it is not a high-rise, the distance is not too close, and it can generally be received.

If you can provide your area, the height of the building in front of you, the height of your home and the distance between the two buildings, it can help you calculate whether it will be affected.

The satellites that relay television broadcasts are geostationary satellites, located above the equator, and we live in the Northern Hemisphere;

If you're in Australia or New Zealand, it's north.

The satellites that relay television broadcasts are all geosynchronous satellites, located above the equator, and our country is located in the northern hemisphere. So it must be oriented southeast, south, southwest.

A considerable number of the current satellites are equatorial satellites (receiver southward), and geostationary satellites account for a small proportion (receiver upward, or basically upward).

Equatorial satellites. South.

Geostationary satellites. Above.

The star that received the most satellites in the southwest direction.
