In the world of satellites, there are two different types of signals: broadcast and direct-to-home (DTH). Broadcast satellites are used to distribute television signals over large areas, whereas DTH satellites serve individual households. In order for a DTH system to function properly, it requires a strong satellite signal that can be received by all subscribers. You may be wondering how you can increase your satellite signal strength? Read on below as we discuss this topic in detail!

What is DTH?

DTH stands for Direct to Home. It is a system of broadcasting television signals directly to the home without any cable or satellite dish.DTH is a digital service and can be used in India and other countries, where there are no high-speed Internet connections available. DTH subscribers receive all their channels via an aerial or by using their set-top box (STB).

The STB receives all signals from various broadcasters across India, who then distribute them to individual households via fiber optic cables or microwave links that connect homes with each other over long distances.DTH services have been around since 1993 when Tata Sky introduced it as an alternative way for viewers to get access to popular TV shows without having to install expensive equipment such as receivers/cables etc.

Components of DTH Technology

DTH (Direct to Home) System consists of the following components:

1. Dish Antenna
2. LNBF (Low Noise Block Down Converter plus Feedhorn)
3. Coaxial Cable
4. Set-Top Box

For example, if you are watching TV while at home but want to watch it on your phone or tablet, then you will need to use an antenna with a digital tuner. Those who live in urban areas can also watch their favorite shows on their smartphones by using apps like Netflix and Amazon Prime.

DTH (Direct to Home) Technology Architecture

To understand how the DTH technology works, you need to understand the system , we must first know that what the technology architecture is and how it works:

Two Bands to transmit Satellite Signals

There are two bands used to transmit satellite signals. The Ku band and C band.

The Ku band: It is used to transmit signals from earth to satellites. It has a frequency of 24 GHz and the channels can be up to 12 GHz wide. This means that a single transponder will handle up to 12 channels at once, but there are also multiplexers that allow you to add more channels onto your transponder if needed (upwards of 56).

The C band: It is used to transmit signals from satellites to earth. It has a frequency range of 5 GHz and can be up to 2 GHz wide. This means that a single transponder will handle up to 2 channels at once, but there are also multiplexers that allow you to add more channels onto your transponder if needed (upwards of 32).

The compression standards used for broadcasting DTH signals

The compression standards used for broadcasting DTH signals are MPEG-2, MPEG-4 and H.264. These three types of compression algorithms can be used to transmit the same amount of data with a smaller number of bits, which means that you will get better quality when compared to other methods like CIF or QAM modulations.

How does Direct to Home Technology Work?

Satellites are located approximately 35,700 kilometers above the Earth’s surface. The satellites transmit signals to broadcast stations on Earth’s surface. The broadcast center receives the signals, and transponders on the satellite help to establish communication channels between transmitting and receiving units. The satellite rebroadcasts these encoded signals, which are combined by multiplexers into digital format.

Satellites being used by Indian DTH operators

As you know, Indian DTH operators use geostationary satellites to send their signals. They also have an option to use foreign satellites as well.

6 Ways to Improve the Signal Strength of Your DTH Satellite

Follow the few of the best recommended tips to increase the satellite signal quality for DTH:

Troubleshoot for Increase Satellite Signals

First, you should troubleshoot the problem yourself by adjusting your dish antenna in the right position. Align your DTH antenna and move it slowly-slowly in right and left direction and same up and down. If you are not able to increase DTH signals, then check for problems with these parts and accessories of your DTH connection.

If you’re still facing issues, check each component of your DTH connection:

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. To check the quality of the signal, slowly rotate the LNB left and right while watching a channel. Only certified LNBs are guaranteed to work properly with your satellite receiver, so be sure to buy from a reputable dealer online.

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 inspect the DTH antenna’s rear screws and nuts.

Replace / Clear Connectors:

Remove the LNB connector from the set-top box and trim any excess wire. Then connect the wires in a clockwise direction around the LNB.

Coaxial cable:

If you are getting weak signals, check the coaxial cable. If you can’t figure out what’s wrong with the cable, replace it. Because if you don’t, it can cause internal damage that we are unable to detect.

Others:

Alternatively; to improve the signal strength of your DTH satellite, use a signal booster for DTH. It is a small device that boosts the signals from your DTH satellite and amplifies them so that they can be received properly by your television set or receiver. There are many different types of boosters available in the market today, but we recommend using one with an external antenna because it helps improve both indoor and outdoor reception quality.

External Factors To Increase DTH Signal Strength

The strength of a signal can vary depending on many factors including weather conditions, location and interference from other sources. Some of these factors include:

• The location of the dish and how it’s aligned to the satellites (the angle at which it points).
• The type of antenna you use.
• The environment around the dish and how far away from other objects, like buildings or trees, they are located in relation to one another.
