5 Simple Actions or Less to Boost your Multi-DTH Signal:


DTH is a satellite transmission service that allows us to watch TV channels on our televisions. This service is now widely available and can be accessed from anywhere in the world.

However, while the majority of transmissions and broadcasts are continuous, they may not be clear or may stop entirely in rare circumstances or conditions. Signal problems are the primary cause of this. You may not be able to see the TV coverage properly if the signal received by the dish is poor.

As a result, we’ve listed the best ways to boost your signal to ensure you have a great viewing experience with your DTH connection. However, before we get started, let’s define DTH and how its signal works.

What Is DTH?

Satellite television transmits video signals from satellite systems in geosynchronous orbits 35,786 kilometres above the equator. An outside parabolic reflector antenna, also known as a satellite dish, and a low-noise block down-converter are used to collect the signals (LNB). A satellite receiver decodes the requested television show and displays it on a television set.

Receivers can be separate set-top boxes or television tuners built into the device. Furthermore, broadcast transmissions may or may not be encoded. In India, for example, the DD Free dish transmits unsecured signals that only essential set-top boxes can decipher. Corporate operators, on the other hand, such as Tata Sky, Videocon D2H, Dish TV, and others broadcast encoded signals that are decoded using data stored in your smart card’s microchip.

Satellite television signals are transmitted in two bands:

  • C band: This band consists of Analogue or Digital transmissions in the 4 to 8 GHz frequency band for Television Receive Only (TVRO) broadcasts and requires a larger dish antenna (6 to 8 feet) to acquire the signals and is not affected by severe weather conditions such as rain.
  • Ku band: This band is made up of Digital signals in the 12 to 18 GHz frequency band that are used for Direct to Home (DTH) telecast and requires a smaller dish antenna (2 to 4 feet) to obtain the more oriented signals but is vulnerable to power outages during bad weather conditions such as heavy rains.

What Is DTH Satellite Signal & How Does It Work?

To evaluate how this system works, it is necessary to first understand that a direct to home (DTH) or direct broadcasting (DBS) satellite system is comprised of five essential components:


Source of Programming

These are the channels that provide programming for broadcasting. Consider HBO, NBC, CBS, Showtime, and the majority of the other channels you enjoy and are familiar with. The supplier charges a fee for the right to transmit their content via satellite. Cable TV providers also operate in this manner, but the similarities end there.

Broadcasting Center

The broadcast centre serves as the system’s central hub. The TV provider receives signals from channels and programming sources at the broadcast centre before sending a broadcast signal to satellites orbiting far above the Earth. To ensure that the signal travels as quickly as possible, it is condensed.


The satellites receive these signals from the broadcast station and transmit them to Earth.

Satellite Television

The satellite in your backyard or on your roof receives the satellite signal and sends it to your home’s receivers.


The receiver decodes the signal and sends it to your television. Even if it appears to be magic, it is all science.

Technically, it is quite complex, but as you can see, the procedure is relatively simple and straightforward. Furthermore, it is remarkable that satellites thousands of miles above us can generate a moving image on our screens.

Multi-DTH Connection

Installation Process Multi-DTH :

In addition to these five elements, DTH signals are transmitted using two types of compression standards:

  • MPEG 2- This is an outdated signal compression technology used by existing DTH companies such as Dish TV, but a DD-free dish, with each transponder carrying approximately 20 SD channels (Fewer in case of HD).
  • MPEG 4- This is a modern signal compression technology that was introduced in 1999 and is currently used by larger DTH operators in India, including Airtel Digital, Videocon D2H, Reliance Digital TV, Sun DTH, and Tata Sky, which has completed the transition from MPEG 2 to MPEG 4. Using this compression technique, each transponder can carry approximately 40 SD channels (Fewer in case of HD).

In India, there are now six private DTH providers and one government DTH provider. The Department of Space (DOS) allows DTH operators to use only satellites licensed by the Indian Space and Research Organization (ISRO). If ISRO satellites lack sufficient capability, they can use capability leased by ISRO from international satellites.

ISRO plans to launch three GSAT communications and broadband satellites over the next two years. The primary goal of these operations, with the exception of those in the ‘C’ Band, is to replace transponders leased by international satellite players.

Improve the Signal Strength of Your DTH Satellite

When experiencing problems with DTH coverage, the first step is to ensure that the antenna is properly positioned. To do this, move the antenna up and down, left and right, and check the signal quality each time.

If you’re still having problems, the next step is to inspect each component of your DTH connection:

1. LNB

The LNB is a critical component in receiving satellite signals. It converts GHz satellite signals to MHz so that set-top boxes can decode music and video. You can check the quality of the signal by slowly rotating your LNB left and right. Use only certified LNBs, which are easily found online.

2. Digital TV Antenna

The dish antenna must be tightened with the screw due to high wind force. If your dish antenna is not properly anchored, it will not receive adequate amplification from the satellite. You can secure your dish antenna to the walls and floor with newer fasteners, and you can also inspect the DTH antenna’s rear screws and nuts. This implies that it should be snug on all sides.

3. Renew or remove connectors

Remove the connector from the LNB, then trim the 2mm excess wire before replacing the connector. Connect the wire to the LNB right away. Repeat the process on the sides of the set-top box.

4. coaxial cable

Are you getting weak signals? Don’t be concerned; simply double-check your Coaxial cord. If you can’t figure out what’s wrong with the cable, you could replace it. Because it can cause internal damage that we are unable to detect.

5. Increase the size of the satellite dish

After you’ve done everything else, the most important thing you can do to improve a satellite dish’s signal strength is to increase its size. For example, if you were previously using an 8ft dish antenna and were unable to obtain or receive a signal, you can increase the size of the dish to 12ft.

External Factors To Increase DTH Signal Strength

Aside from the components of your DTH connection, there are some external factors to consider and correct if necessary to increase DTH signal strength. We’ve covered some of the most common external factors that are simple to address.

Remove any major obstacles

The satellite dish must be installed or sited in an area free of obstacles such as buildings, plants, and mask networks. Position your antenna at least 15m to 20m away from any obstruction to improve satellite signal strength.

Make use of a Scaler Ring:

A scaler ring serves two purposes. The first is to increase the signal strength of the dish antenna for a satellite that your geographic location does not cover; thus, the scaler ring will increase the signal strength from 5% to 10%.

The C-band signal is collected on the KU band dish antenna in the second function.

Scaler rings were first introduced about 2-3 years ago with an aureole power VU receiver for receiving Sports 24HD with a 1 m dish antenna, and then encrypted with a new algorithm.

The Dish Stand and Pole must be Securely Fastened:

The signal strength frequently drops if the platform or poles are not properly upright and perfectly connected while installing or standing.

To improve the direct tv satellite signal strength of the dish antenna, ensure that the pole or stand creates a 90-degree angle to the Earth’s surface.


DTH is an excellent alternative to cable TV; however, if the content is of poor quality and frequently interrupted, it does not do this technology justice. As a result, if you’re having problems with your DTH signal setup, consider using the tips provided above to ensure a smooth experience!
