When will the satellite dish go off the air?  Why digital antenna does not pick up?  See the main doubts about the change in the TV signal |  Technology

  • 5G INTERNET: understand the new technology

As the change still raises doubts, O g1 gathered some of the top questions asked on the internet on the subject and sent it to specialists from two brands of antennas.

See the answers below.

1. When will the satellite dish go off the air?

The signal from the old satellite dish is scheduled to be turned off in early 2024. If necessary, this period may be extended to December 31, 2025.

change happens due to the activation of the new generation of mobile internet, 5Gwhich operates in frequency bands close to the signal from the old satellite dish and can cause interference.

The lane is like a “highway” in the air, along which the signals travel.

Helio Cesar, New Business supervisor at Century, says that the 5G signal is more powerful than that of the satellite dish. “The frequencies are very close, and this causes the 5G signal to interfere with the old satellite dish, making it impossible for the two technologies to coexist”, he explains.

With the end of the old signal, an alternative will be to use the new satellite dish, which works in another band.

2. Is the satellite dish analog or digital?

It depends on which antenna you are using. The old satellite dish, which works in the frequency range known as Band C, the same as the 5G internet, is capable of receiving both analogue and digital signals. In the second case, however, she needs a digital TV receiver.

The new satellite dish, which operates in the Ku Band, only receives the digital signal. It is the same case with the “herringbone” and internal antennas. See the difference between them below.

3. How does a satellite dish work?

The dish is a kind of reflector of the signal that comes from the geostationary type satellite, which is about 35,000 km from the Earth.

This signal bounces back to the pickup (also known as LNB, which stands for “low noise converter”), which sits in the center of the structure.

The signal received at the pickup is converted and then processed by the receiver that is close to the TV.

4. In what situation is the dish indicated?

A new satellite dish maintains the free TV signal and offers image and sound with better quality than the old antennasas well as new channels and regional programming.

“This type of signal is very suitable for those who are far from the big centers, where the offer of local channels is reduced, especially in the rural zone”, explains Helio Cesar, from Century.

5. Why doesn’t the digital antenna pick up?

Several factors can cause problems with your new dish. Some of the most frequent ones involve pointing the antenna and assembling connectors, explains Vivensis co-founder Yvan Cabral.

He also says that it is important to pay attention to the place where the antenna will be placed. “The higher and out of reach of children and animals, the less problems it will present”, he says.

6. Where to place the antenna?

The new dish is simple to install and just needs to be placed in a location that has no obstacles to communication with the satellite, such as trees or buildings.

The recommendation is to leave it in high places, such as walls, roofs or slabs. The orientation is that it be installed by a specialized professional.

7. What is the price of the new dish?

The new satellite dish kit, including antenna, receiver, control and cables, cost between BRL 500 and BRL 700 in internet stores, in early 2023.

But there are cheaper alternatives, such as the “herringbone” antennas, which cost around R$70, and the internal antennas, which can be found for approximately R$30.

You can order the new antenna for free if you meet two requirements:

  • have an old/conventional dish that is working;
  • be part of CadÚnicoa system that includes beneficiaries of some federal government social program, such as Auxílio Brasil (formerly Bolsa Família), Social Electricity Tariff, ID Jovem, Carteira do Idoso and Casa Verde e Amarela.

In addition, your city must already offer the exchange of equipment. Currently, this happens in the capitals and in another 480 municipalities.

To find out if you can order the new dish, and if you can start the process, go to this website or call 0800 729 2404.

8. How do I know if I’m on CadÚnico?

The CadÚnico website and application allow you to check if you are in any social program. To do this, simply enter your personal data.

9. How to tune the new dish?

The new satellite TV systems have features for you to add channels yourself. But the tip is to leave the tuning of the channels to a technician, who correctly points the antenna to the satellite and leaves the channels configured for the customer, says Yvan Cabral, from Vivensis.

“In practice, consumers only need to use the remote control and navigate to the channel they want. It’s very similar to what we have today with digital converters and cable TV decoders, where we turn on and all the channels,” he says.

10. Why does the satellite dish have a bad image?

As the new satellite dish uses a digital signal, it is very unlikely that there will be drizzle in the image, as happened with the analog signal. On the other hand, there may be problems with the signal quality, which causes constant freezes in the image.

“In this case, the best thing to do is request a visit from a technician specialized in antennas to check what is happening”, advises the Century representative.

The professional will be able to make tests with the equipment, including the antenna, the pickup and the receiver.

The review also includes “an analysis of the connectors and the location of the cables, because if they are close to the electrical network they can generate an electromagnetic field, which hinders the transmission”, says the specialist from Vivensis.
