DTH is a service that allows us to watch TV channels on our television via satellite transmission. This service is now quite widespread, and it can be accessed all around the world.

However, while most transmissions and broadcasts are uninterrupted, they may not be clear or may cease entirely in rare circumstances or conditions. The primary cause for this is signal issues. If the signal received by the dish is poor, you may be unable to see the TV coverage adequately.

Hence, to ensure you’re able to enjoy a great viewing experience using your DTH connection, we’ve listed the best ways to increase your signal. Before we get started, however, let’s get a better understanding of what DTH is and how its signal works.

You can use a non-stick cooking spray oil to coat your DD Freedish antenna. Raindrops adhering to the DTH antenna can cause it to receive DD Free dish signals irregularly, therefore this spray keeps them away.

What Is DTH?

Satellite television provides television content using signals sent from satellite systems in geosynchronous orbits 35,786 kilometers over the equator. The signals are collected using an outside parabolic reflector antenna, often known as a satellite dish, as well as a low-noise block down-converter (LNB). The requested television show is subsequently decoded by a satellite receiver and displayed on a television set.

Receivers can indeed be separate set-top boxes or television tuners incorporated within the device. Moreover, broadcast transmissions might be encoded or not. For example, in India, DD Free dish transmits unsecured signals that essential set-top boxes can decipher. On the other hand, corporate operators like Tata Sky, Videocon D2H, Dish TV, and others broadcast encoded signals that are decoded using data in your smart card's microchip.

Satellite television signals are sent in two kinds of bands:

  1. C band: This band consists of Analogue or Digital transmissions in the 4 to 8 GHz frequency band to use for Television Receive Only (TVRO) broadcast and requires a bigger dish antenna (6 to 8 feet) to acquire the signals and is unaffected by severe weather conditions such as rain.
  2. 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 needs an even smaller dish antenna (2 to 4 feet) to obtain the more oriented signals but is vulnerable to power failures throughout bad weather conditions such as heavy rains.

What Is DTH Satellite Signal & How Does It Work?

To understand how this system works, we must first know that a direct to home (DTH) or direct broadcasting (DBS) satellite system consists of five essential aspects:

  1. Programming Source

    This is referred to the channels that supply programming for broadcasting. Consider HBO, NBC, CBS, Showtime, and most of the others you love and know. The supplier charges for the right to transmit their material through satellite. Cable TV providers also operate in this manner, but here is where the parallels end.

  2. Broadcast Centre

    The broadcast centre can be considered as the system's core hub. The TV provider receives signals from channels and programming sources at the broadcast centre, then shoots a broadcast signal to satellites into the orbit far above the Earth. The signal is condensed to ensure that it travels as quickly as possible.

  3. Satellites

    These signals are received by the satellites from the broadcast station and transmitted to Earth.

  4. Satellite Dish

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

  5. Receiver

    The signal is processed by the receiver and sent to your television. It's all science, even if it appears to be magic.

Technically, it is rather complex, however as you can see, the procedure is relatively easy and uncomplicated. Moreover, when you consider that satellites thousands of miles above us can generate a moving image on our screens, it's remarkable.

In addition to these five elements, there are two kinds of compression standards used for transmitting DTH signals:

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

In India, there are now six private DTH companies and one government DTH provider. The Department of Space (DOS) allows DTH operators to utilize only satellites licensed by the Indian Space and Research Organisation (ISRO). If ISRO satellites do not have enough capability, they can use capability leased by ISRO from international satellites.

ISRO intends to launch three GSAT communications and broadband satellites during the next 2 years. The primary goal of these operations is to supplant transponders leased by international satellite players, with the exception of those in the 'C' Band.

Increase the Strength of Your DTH's Satellite Signal

When facing issues with the coverage of your DTH, the first step is to check if the antenna is set in the proper position. To do this, you need to slide the antenna up and down and left and right, and each time check the signal quality.

If you’re still facing issues, the next step is to check each component of your DTH connection:

1. LNB

The key component of receiving satellite signals is the LNB. It takes satellite signals in GHz and transforms them to MHz so that set-top boxes can decipher music and video. You may test signal quality by slowly rotating your LNB left and right. Only use certified LNBs, which are easy to find online.

2. DTH Antenna

Due to high wind force, the dish antenna must be tightened with the screw. If your dish antenna is unsecured, it will not get adequate amplification from the satellite. You may use newer fasteners to secure your dish antenna to the walls and floor, and you can also inspect the DTH antenna's rear screws and nuts. This implies it should be tight on all sides.

3. Renew or Clear Connectors

Disconnect the connector from the LNB, trim the 2mm excess wire, then replace the connector. Connect the wire to the LNB immediately. Do the very same procedure on the set-top box's sides.

4. Coaxial Cable

Getting weak signals? Don't worry; just double-check your Coaxial cord. If you can't identify a problem with the cable, you could replace it with a new one. As it can create interior harm that we are unable to detect.

5. Increase Satellite Dish Size

After you've done everything else, the most significant thing you can do to improve the signal strength of a satellite dish is to expand its size. For example, if you were previously utilizing an 8ft dish antenna without obtaining or receiving a signal, you can expand the size of the dish to 12ft.

External Factors To Increase DTH Signal Strength

Besides the components of your DTH connection, there are some external factors that you should consider and fix if needed to increase DTH signal strength. We’ve mentioned some of the most common external factors you can fix without any hassles.

Remove Any Obstructions

The satellite dish must be mounted or sited in an area devoid of obstructions such as buildings, plants, and mask networks. To improve satellite signal strength, position your antenna at least 15m to 20m apart from every obstruction.

Use a Scaler Ring

A scaler ring has two main functions. The first is to boost the signal strength of the dish antenna for a satellite that your geographic position doesn't really cover; thus, the scaler ring will significantly raise the signal strength from 5% to 10%. The second function is to collect the C-band signal on the KU band dish antenna. Scaler ring was introduced approximately 2-3years ago with an aureole powerVU receiver for receipt of Sports 24HD with 1 m dish antenna, and then with a new algorithm, it has finally been encrypted.

The Dish Stand and Pole Must Be Properly Mounted

If the platform or poles are not correctly upright and not perfectly connected while installing the poles or standing, the signal strength often drops. You must ensure that the pole or stand must create 90 degrees to the Earth's surface to improve the dish antenna's direct tv satellite signal strength.

The dish may be out of alignment with the satellite due to bad weather. You'll need to realign your antenna for this.


DTH connection is the perfect alternative to cable TV, however, if the content is in low quality and is interrupted, it doesn’t do justice to this technology. Hence, if you’re facing any challenges with your DTH signal, consider using the tips given above to ensure you can enjoy a seamless experience!
