How To Pick The Right KU Band LNB For Satellite TV Dish

How To Pick The Right KU Band LNB For Satellite TV Dish

This website page is dedicated to assisting you in choosing the right KU LNB or KU Band LNB for your satellite dish. As there are numerous differing types, makes, and models, pick the incorrect one could mean that your satellite TV won’t work. In this tutorial, I will be discussing what is an LNB?, what an LNB does? And What types of LNB’s available used on various satellite TVs services like DStv, Sky, Cosmote TV,  and Freesat! And how to choose the right KU Band LNB for your satellite. Let’s begin.

What is KU Band LNB?

The LNB, which stands for Low Noise Block, is that the attachment at the top of the satellite dish during which the coaxial cables that feed your receiver.

Each different sort of LNB works in its way. Still, one of the most functions is to require the amplify the satellite broadcast signal. Oscillate the signal to a lower frequency band that the coax can contain without excessively cable losses. Therefore, the higher the frequency, the more excellent the cable resistance, and the quicker you’ll lose signal down the cable.

Most LNB’s, but not all of the oscillate the signal right down to the satellite intermediate frequency band, which is between 950Mhz to 2150Mhz.

How Does A Universal KU Band LNB Work?

Universal LNB’s work by varying a supplied voltage form the satellite TV receiver which can switch the LNB between receiving horizontal and vertically polarized signals. And by applying continuous 22Khz tone, it turns the LNB between a high and low band. It does this because the bandwidth on the transmission is bigger than the bandwidth available on the coaxial cable.

It suggests that, there’s the only ¼ of the available satellite services on the coaxial cable at anybody time. Therefore, you can’t just split a satellite signal off a universal KU Band LNB. And the separate cables got to installing with different direct connections to the LNB, which I will be able to explain more on shortly.

For your reference, universal LNB’s oscillate signals within the KU satellite band, which is 10.7Ghz to 12.75Ghz right down to the IF satellite band, 950Mhz to 2150Mhz.

  • Low band signals oscillate the frequencies between 10.7Ghz-11.7Ghz by 9750Mhz
  • High band signal oscillates the frequencies between 11.7Ghz-12.75Ghz by 10600Mhz.

Below are the useful guides for remembering what satellite bands what DC voltage is and or 22Khz tone will get to be applied by the receiver to receive them.

  • Vertical Low (VL) – 13V
  • Horizontal Low (HL) – 18V
  • Vertical High (VH) – 13V+22Khz
  • Horizontal High (HH) 18V+22Khz

Types of Universal KU Band LNB’s

There several kinds of universal KU Band LNB, the most common ones are single LNB’s and Quad LNB’s. The difference between all of them is that the amount of outputs that the LNB itself has, this enables extra satellite receivers to add for extra TV points.

And for the addition of satellite PVR’s that has recordable, pause, play and rewind TV services, like Sky+ and Freesat+that require two separate KU Band LNB connections to figure correctly.

How To Pick The Right KU Band LNB For Your Satellite TV Dish
Inverto Black Ultra Single LNB For European Satellite tV

Single LNB (1-Ways)

A single KU Band LNB features a single LNB connection for a coaxial cable to be connected. It may allow you to connect a typical satellite receiver like a Sky or Freesat box. You’ll plug a Sky+ or Sky+HD box, but the Skybox must set to single feed mode, and you’ll lose the power to record one TV program and watch another.

Inverto Black Ultra is the best example and the right choice to most of the European satellite tv like Yes tv on Amos 4, Cosmote TV, Astra 28.2E, Astra 19.2E and so on.

How To Choose The Right KU LNB

Dual LNB (2-Ways)

These type of LNB’s not common, but used to make new satellite connections or to install a satellite dish for the first time to only install a Quad LNB instead as this may future proof the installation further and allow for more two connections. The value difference isn’t that much.

Actually, Quad KU Band LNB’s are often cheaper thanks to them being installed and produced in higher volumes. A Dual LNB will leave two separate satellite receivers to be connected or a one satellite PVR.

If you’ve got recently upgraded to Sky Q and see that your LNB has two connections only, please remember that this is often not a dual LNB but a Sky Q wideband LNB that works very differently.

How To Choose The Right KU Band LNB For Your Satellite TV Dish

Quad LNB (4-Ways)

Quad LNB’s are the most common LNB installed mostly viewing center for DStv collective or extra-view at the same reception, and that I install them as standard with all our standard Sky and Freesat installations.

A Quad LNB will allow up to four satellite receivers to be connected, two PVR’s or one PVR and two standard satellite receivers. If more connections are required, then the LNB must be upgraded to an Octo LNB.

How To Choose The Right KU Band LNB For Your Satellite TV Dish

Octo LNB (8-Ways)

Octo LNB’s as I’m sure that you simply can guess have eight separate outputs allowing eight coaxial cables to be connected and feeding up to eight different satellite receivers, four PVR, or a mixture of both. If you would like more connections off one satellite dish, unfortunately, there aren’t any freely available LNB’s that leave more connections. Instead, a replacement approach must be adopted. The installation of a Quattro LNB, which is hugely different from a Quad LNB and a multi-switch amplifier.

Right KU LNB For DStv

Smart LNB’s Used For DStv, Freesat & Sky

As both Sky & Freesat both use an equivalent satellite for his or her services, which is located at 28.2E, the precise same satellite dish and LNB are often used. It is usually perfect for when people wish to cancel their Sky subscriptions as they will still receive Freesat through an equivalent satellite dish.

If you’ reusing an MK4 style Sky mini-dish satellite dish, then the LNB must have a 38mm collar and not a 40mm collar; otherwise, it won’t fit the LNB holder on the satellite dish. Adapter holders are often purchased to accept a 40mm collar simply, but it’s only one other thing to order in or confine stock, so I advise ordering the right LNB to start with. I won’t undergo all the various types again as these are single, Quad and Octo LNB’s.

The smart LNB can be used to connect Collective and Extra-View and it is mostly used in Nigeria among the viewing center and hotel. This DStv smart LNB can be used to receive DStv signal point to Eutelsat 36A at 35.5E and Intelsat 68.5E.

Sky Q Wideband LNB

You may or might not remember that Sky Q uses a new sort of LNB to traditional Sky and Freesat. I’m sure that they need their reasons for doing this but making it harder to cancel your Sky subscription. And attend Freesat will now involve changing the LNB on the satellite dish also because of the receiver itself.

How Does A Sky Q LNB Work?

It’s good that I even have already gone over how universal LNB’s work because it will assist you in understanding the Sky Q LNB and the way the Sky Q LNB is different from a universal LNB. Sky Q LNB’s have two separate cable inputs sort of a dual LNB, but they work very differently.

One cable is connected to a vertical output and, therefore, the other a horizontal output. There’s no switching off the LNB between horizontal and polarised signals as both the cables are carrying different services.

It suggests when employing a Sky Q wideband LNB that the Sky Q box must be connected with two cables that must be connected to receive all the services and channels. There are ways of connecting a Sky Q box with one cable, as I mention the blog afterward.

For the sharpest among you’ll be wondering why all similar services are often fitted onto the two cables without the necessity for a high and low band oscillator? This is usually because the LNB uses a higher frequency range than universal LNB’s do.

This is often between 300Mhz-2340Mhz, meaning that it steals bandwidth, which wont to be reserved for TV aerial signals indicating that now switching at the LNB is essential. This, however, does present big problems with diplexed TV and satellite systems and communal IRS systems because the Sky Q and tv aerial signals can not be combined onto the same cable.

How To Choose The Right KU LNB For Your Satellite TV Dish

Hybrid LNB’s

A familiar and welcome addition is that of hybrid LNB’s. These are a mixture of the wideband LNB used for Sky Q and Quad LNB’s used for standard Sky and Freesat. This suggests that one satellite dish wont to connect a Sky+HD or Freesat box up one room and a Sky Q box up another, and this enables us to future proof the satellite dish installation as much as possible and provides greater flexibility to our customers. Hybrid LNB’s accompany six outputs, and not all hybrid LNB’s are equivalent.

Some allow either a Sky Q or standard Sky/Freesat box to attach to every single output of the LNB. Others have two wideband outputs and four universal outputs. The latter meaning that if you would like to make sure that the cables that feed each receiver corroborate with the connections on the LNB, otherwise, it’ll not work.


Although this sort of LNB is often used for varied satellite TV systems abroad, the sole reason you’d typically install this LNB type within the UK is for Sky Q, so this section has been written with this in mind.

A dSCR or dCSS LNB will allow a Sky Q box to be connected on one feed, which is useful for when extra cables. It can’t be installed between your satellite dish and Sky Q box for any reason. Once you do that, you want to change the LNB setting to ‘SCR’ mode on the settings menu on the Sky Q box.

There’s not switching on the LNB again. It instead looks for the frequency of the transponder for the channel that the receiver has requested, and oscillates it to rock bottom available frequency. This enables for multiple programs to be recorded at an equivalent time without the necessity for extra satellite LNB connections, as required with universal LNB’s.

The LNB oscillates right down to the Intermediate frequency band, which begins at 950Mhz and means a terrestrial aerial signal is often combined onto a similar cable, making it the LNB of choice for diplexed TV/ Sat systems that aren’t employing a multi-switch amplifier. dSCR technology is what’s used with Sky Q compatible communal systems.

Worthwhile mention – dSCR + Universal Quad LNB

There is another dSCR Quad LNB on the market, which has one SCR output for connecting a Sky Q box onto one feed mode and three traditional universal LNB outputs for connecting ordinary Sky or Freesat boxes.

Quattro LNB – For Communal IRS & Satellite Systems

When you install a communal IRS TV system, traditional LNB’s can’t be used because the amount of connections required is typically far higher than available on an Octo LNB. For this reason, a replacement approach must be adopted, and this is often done via a Quattro LNB and multi-switch amplifiers. This blog isn’t about the installation of communal TV systems so that I won’t enter great detail here.

Although a Quattro and Quad LNB both have four outputs. A Quattro LNB differs within the sense that it supplies the four satellite bands separately over the four cables, whereas a Quad LNB switches between all of them of all the cables. This means that it can’t be connected to a receiver when installing a Quattro LNB.

It must be connected to a multi-switch amplifier with separate VL, VH, HL, and HH inputs where the switching instead takes place. Therefore the cables must not be mixed from the LNB and the input of the amplifier. By using this idea, only four cables got to be installed between the satellite dish. And the multi-switch amplifier concept are often extended to serve many satellite TV points.

As there’s switching from the KU Band LNB, providing you’re employing a splitter that’s both DC passing and capable of serving the satellite IF band frequencies. The signals are often split between multi-switch amplifiers. Just remember that you simply will need four separate splitters or a splitter with four different inputs.

How To Pick The Right KU Band LNB For Your Satellite TV Dish

Monoblock KU Band LNB

A Monoblock LNB is an LNB with two separate feed-horns. It is effectively two different LNB’s combined into one with a 6-degree separation, making it perfect for combined Astra 1 (19.2E) and Hotbird (13E) installations.

A Monoblock LNB designed to be used with 80cm satellite dishes or larger size for signal reception. It has one cable output for connecting to a DiSEqC compatible receiver, which will be set up to be ready to switch between the various LNB signal inputs.

High Gain KU Band LNB

You may have encountered the term “high gain” LNB. To know this, it’s best to consider the LNB because of the first stage of amplification. As satellite signals are beam right down to earth is insufficient strength. One among the most roles of the LNB is amplify the signal. Most LNB’s are around 50dB gain, but some models, High Gain LNB’s could also be about 60dB gain or more.

These LNB’s are intend to be used with long satellite cable, runs where the cable resistance could cause loss of signal. It’s not a realistic idea to put in these in situations with short cable extensions as you’ll overload the receiver and cause poor TV reception.

There Are Loads More On How To Pick The Right Ku Band LNB

There are loads more differing types of LNB, like LNB’s used for fibre installations or NBC’s. It is used for a few satellite broadband installations and that I may update this blog at a later date. But I’m not getting to enter them here at this point.

As usual, you’ve got any LNB or satellite related questions, please LEAVE A COMMENT within the blog comment section below. Please don’t CALL OUR TELEPHONE LINES, and please don’t E-MAIL us. We simply don’t have the power to answer all the questions we get asked.

I certainly don’t have the time to talk on the phone every time. And I don’t give out my mobile phone number as is often requested. That being said, I answer blog comments as this provides me a central location to answer all the questions. And everybody reading the blog gets the advantage of the problem asked, therefore, the answer is always provided.

Suggestions On How To Choose The Right KU Band LNB

Here is my suggestion for you on how to choose the right KU LNB for Satellite dish as follows:

  1. Product name determined the quality of the lnb
  2. Check the noise gain according to the analysis given above
  3. Study your local area to determined which LNB will work best for you
  4. Satellite dish size also call for the type of LNB to be used for satellite, the distance the satellite the lowest the signal you will get.

Satellite Dish Not Working: Why And How To Fix The Problems

Satellite Dish Not Working And How To Fix Satellite Dish Signal

Preparing to watch the greatest two finals in this summer, Later you realized that satellite Dish not working or No signal. This is embarrassing, Don’t worry this post will guide you to analyzes the reasons that could be arise why your satellite dish not working and how to fix satellite dish signal problem or no signal. Let’s examine them one after the others

Reasons Why Your Satellite Dish Not Working And How To Fix It

No Signal On Satellite Dish

To get maximum signal level, Then your satellite dish needs to be aligned correctly to avoid loss of signal, It is not proper to align a satellite dish by eyesight alone or by mere looking at the others house’s satellite dish. simply because of the way they work and the transponders/frequencies that they use. There’s a big differences between a signal with good quality signal and no signal at all. Increase or little adjustment to realign your satellite dish already knocked off direction could be the reason why your satellite dish not working and this is how to fix satellite dish signal problem.

You need to understand and keep in mind the following, The elevation and the screw, The east and the west, The adjustment on the LNB itself. For instances, Beoutq and Sky both faces East and this explain deviation off due south. Due to the fact that it is beaming the signals down to the earth from an angle. Adjustment must be made on the satellite dish to make rooms for this. And the LNB itself explain the phenomena of vertical and horizontal polarized signals to fix satellite dish signal problem. Anyway here are some tutorials on watch European and US TV.

Satellite dish not working or no signal, Suppose you want to try it by yourself, It is highly recommend to use signal finder or TV Spectrum analyzer as you can watch everything on the screen when the high quality signal is achieved. Surely, Not everybody owns or have access to satellite alignment tools. It can be purchased via online or local shops. Make sure you have idea of what direction you are pointing the dish as important.

How To Determine The Location Where Dish To Face

To fix satellite dish not working or fix no signal problem, You’ve to determine where to point your dish, then you need to satellite co-ordinates like dishpointer for easy installation, You just need to enter your postcode and the satellite you wish to install or use, And it will give you all the information on both east and west alignment angle, the elevation and the screw adjustment. It will help you with indication of line of signal for you to use as a reference.

I strongly recommend using compass and inclinometer while making attempt to aligning your satellite dish. Don’t forget to consider the allowances differences differences due south and magnetic south usually change.

Weathering/Waterlogged Cables

Due to the facts that satellite antenna needs to be install outside and because LNB requires satellite receiver to work together as a unit. It is good to cover all the connection made to the coaxial and the LNB itself. To avoid satellite dish signal problems, There should be adequate weatherproofing measures put in place to prevent any rainwater onto the inside of the cable. Here are the common ways to prevent weatherproofing or waterlogged.

A. It is very easy for water to get inside the coaxial cables if the weatherproofing cover on the LNB is pulled down, Most especially when you are in seaside or coastal region, You have to ensure that the cover on the LNB is well placed down.

B. The F-connector is expensive and requires specific tools to put them onto the cable for tight connection. One need to use weatherproof F connectors.

C. Ensure that silicone grease are pour on the top of weatherproof plugs and other connections joint. I strong recommend it for satellite engineer in order to keep the outside of the plugs in perfect order.

D. Ensure that you put amalgamating tape to the top joins and to ensure a good weatherproof. Suppose your satellite signal is not working and you realized that the connectors themselves are waterlogged. cut off the affected part to make another cable connectors. If you see that the inside of the cable has rust, wet and partial contact, It will be good replace the whole of the cable.

Satellite dish Obstruction

Obstructions Or Trees Blocking The Satellite Signal

Why your satellite dish not working, Obstructions could be a barrier, For Instances Trees, Storey buildings, Mass Communication Antenna and others can block your satellite dish installed nearby this obstructions. It can affect your signal if placed above the Satellite dish.

For your satellite dish to work perfectly, You need clear the obstructed trees, or move your dish itself higher than the trees. You can move the dish away from the obstructed buildings or trees. In any circumstances, A good satellite dish installer or technician needs to consider the location where dish would be mounted. And free from obstructions And this is one the way on how to fix satellite dish signal problems or fix no signal issue.

The following are the temporary obstruction of satellite dish:

  • A nearby Scaffold
  • Cobweb spread either on the dish or inner side of the LNB

The best solution to this problem, You need to clear and clean the particles made by the spiders or any other insects. Also by removing the scaffolds nearness to your satellite dish.

Faulty LNB

It is very much possible that the LNB itself has become faulty and leads to why your satellite dish not working. This is similar to any others electrical devices that can just develop a fault for unceremonious reasons. Satellite dish not working or no signal so long and suddenly fail. Faulty LNB’s can be liable and responsible for it.

There are some LNB’s that develop fault and still appear as if it doesn’t faulty. It can be very much difficult to diagnosing these type of faults. even if you own or borrow high performance test tools as you often check the satellite signals and realized that everything is in order.

If your satellite dish is well aligned and accurate with no obstructions blocking the signal with no significant weathering disorder and during the night seems not to be cloudy when properly checked.

I would strongly advice that the LNB should be replaced. For instance, It happened to me one day while re-aligning the client dstv dish, I worked lengthy, signal seems to be ok on my sat meter but when i try to test the signal on dstv decoder it fail to scan the channels, Later I suggest remove the LNB and test it again. then dstv is able to scan and everything is perfect.

Having said that faulty LNB’s can also be responsible for you lost signal on your dish and it is not easy to diagnose in certain situation than to replace the faulty LNB. And this is how to fix satellite dish signal problems.

Electrical Storms Thunder, And Heavy Rain

Satellite signal reflected back to the earth surface from the satellite in space. Atmospherics and weather conditions can also affect your satellite TV reception. Most importantly cloud rather, electrical storms and heavy rain. The radio wave is an electrical conductor. Radio waves can pass through through conductor, rain and storms. This can also cause why your satellite dish not working.

To fix satellite signal problems or No signal, Certainly, the signal usually comes back after the rain because the storms ceases the signal. If you often lost signal when there’s little rainfall. Then I will recommend you to try any larger satellite dish to increase the signal quality in small amount.

As far as thunder is concern, This usually happened in every, As it is caused by lightening and thunder. It is not possible for thunder to strike without lightening first. whenever there’s lightening, It makes the way for thunder to strike and enter through LNB and later to any connected devices. It caused damage to the LNB either you are watching during the rain or power off. That’s why your satellite dish not working after raining.

To fix the satellite signal problems, I will recommend you to disconnect any home appliances connected to the satellite dish or from the wall socket.

Why Satellite dish signal not wrking

Poorly Disconnected Cables

Why your satellite dish not working! This often occurs as a result of short cable connection between the LNB or receiver. There’s chance for negative charges of the coaxial cable to touch the positive conductor. This would cause the flow of direct current (DC) flowing up to the LNB from the Satellite receiver. This can also cause hardware problem to receiver and leads to why your satellite dish not working.

Other common problem involves poorly disconnected cables includes:

  • Centre conductor is too short and there’s partial connection
  • Plug completely loss the connection
  • Incorrect size of the plug for the cable

To fix satellite dish signal problems in this situation, You have to use enough coaxial cable without any joined. Ensure tight connect between the cable and F-connector and make sure you use original cable satellite TV dish.

Broken Satellite Dish

Since satellite signals are beamed down to earth from satellites in space. It later reflected by the bit round or oval part of the satellite dish antenna through the LNB. If any part of the satellite dish is bent or completely rusty. This can cause the satellite signals to lost any part of the dish. The LNB would not be able to catch any signal

Similarly, If the LNB sit or holder is slightly faulty and can’t hold the LNB perfectly. This could result to the reason why you satellite dish not working. It is advisable to replace the damaged LNB holder.

External Electrical Interference Generated From RF/EMI

Why your satellite dish not working, This often occurs under faulty conditions and should be reported to whomever behind the scene for though checking happens in your environment. Many phones operators or Network providers that use frequencies with the satellite intermediate frequency band (IF).

However, Once in a while, there’s chance for your satellite TV reception to get affected. And you may need to relocate your dish. To fix the satellite dish signal problem, I will recommend to change or replace the LNB with a inbuilt LTE filter components.

Others satellite dish signal problems includes high gained signal. This is rare situation, If the coaxial cable is connected to high gained LNB, there’s chance for you to experience loss of signal. So you have to use a signal attenuator to convert the DC to the normal one that satellite TV uses.

Avoid using more than one joint, Because if the joint is more than one. Then there’s chance to loose signal on your satellite TV. These are the reasons why your satellite dish not working and how to fix satellite dish signal problems.

How To Increase Satellite Signal By 10-15% On KU/C-Band Dish

Focal length increase signal strength of a dish antenna

Learn How To Fix or Increase Satellite Signal Strength Of A Dish Antenna

Many folks out there are battling with poor satellite signal strength and willing to increase it to enjoying their channels. Ku band dish doesn’t have much problem because the manufacturing company has already perfect their work, tested and confirmed working with satellite signal before the sales of the antenna.

However, The signal quality of a C-band Satellite dish can be determined by the materials used for construction, the focal length, sizes, LNB, cable and many more, don’t worry I will get you cover on how to increase satellite signal strength by 10-15% on any C-band dish, Let’s dive in.

Obstructions Remove

Satellite dish needs to be mount or sited where dish will be free from obstacles like buildings, trees and mask network. So to increase satellite signal strength, You have to mount your antenna at least 15m to 20m dish away from any obstacles.

Satellite dish Obstruction

Cable Connection

To increase satellite signal strength of your dish antenna, the cable connector like F-connector should be properly installed and connected to both the receiver and antenna. Preferably use coaxial cable with not more than 25m long i.e connection distance between dish antenna and the receiver.


Choosing LNB with Low db Noise Figure

LNB is another thing you need to consider to increase the signal of dish antenna. LNB with low db noise figure can boost your signal strength and quality with 15% above. For instance inverto Ultra Black LNB has 0.2db which skyrocket the signal strength of a dish antenna And If your M4 Sport HD, Sport 1HD and AFN signal strengh not improve, then you can buy KU Band LNB with 0.2db noise figure.

0.2db KU Band LNB

Using Scaler Ring

Scaler ring features with two important things, One is to increase the signal strength of a dish antenna for a satellite which your geographical location not cover, hence, Scaler ring will increase the signal strength from 5% to 10% and Secondly, Scaler ring helps to receive C-band signal on KU band dish antenna and scaler ring was used to receive Sport 24HD on 1m dish antenna about 2-3years ago using aurole powerVU receiver o opening the channel before it finally encrypted with new algorithm.

Scaler Ring On KU Band Dish

Dish Stand And Pole Should Be Well Mounted

Signal strength usually reduce if the dish antenna standing or pole is not well straight and not properly aligned while mounting the the pole or standing. To increase the Direct tv Satellite Signal Strength of your dish antenna you have to make sure that the pole or standing must form 90 degree towards the earth surface.

How To increase satellite signal strength

Focal Length or Point Must Be Accurate

Focal Point is very important as far as installation of satellite dish antenna is concern because without knowing the focal point or length between the center of the dish to the feed horn or LNB, It will be very difficult to get signal or increase the signal strength of a dish antenna, To learn how to calculate for focal length here.

Focal length increase signal strength of a dish antenna

Using Brass And Removing LNB Cover

Removing LNB Plastic cover always recommended to adopt anytime you are installing KU band dish antenna because it will make your installation fast and safe energy. After removing plastic cover and you still experience lost of signal due to beam or footprint, then using brass with LNB will be essential to increase the signal strength of a dish antenna by attaching the brass to the round surface of the LNB.

Uncover KU Band LNB

Increase In Size Of A Satellite Dish

After you have done all what I said earlier, The best thing you can do to increase the signal strength of a satellite dish is by increasing its size. For instance, if you are using 8ft dish antenna before without achieving or getting signal then, you can increase the size of the dish to 12ft. Same way you can increase Direct tv Satellite Signal Strength.


satellite signal strength can be increase in different approaches depends on the satellite tv you wish to receive, the LNB is very important by choosing LNB with low db noise figure, if you are installing any KU signal on Cband dish like Hotbird, it is good to use 0.2db with accurate dish size and as well as to use accurate focal length.

Satellite TV Guide (An Introduction) & How Satellite TV Work?

Satellite Tv Guide; How does satellite tv work

A complete Satellite TV Tutorial Guides For Beginners

Hi guys, In this tutorial, I will be discussing with you the introduction to Satellite tv guide which will includes the basic knowledge of satellite tv with an appropriates illustrations. You may be wondering how does satellite dish antenna receive signal from the sky and to the receiver. Don’t worry I will get you cover, by the end of this tutorial, you understand how satellite tv work! very interesting.

What is Satellite TV?

according to wikipedia, Satellite TV is a service that delivers television programming in digital form to the viewers or subscribers through the implementation of communication, satellite revolving round the earth and directly to the receiver in their respective homes.

How Does Satellite Dish Works?

The best satellite tv guide for whoever wish to engage in satellite tv installation in the right perspective must know how does satellite tv works. And below are the keywords related to satellite tv guide:

  • Programming Source:
  • DBS Provider Broadcasting Source Center
  • Space Satellite
  • Satellite dish
  • Satellite tv Receiver

Now lets take these keywords one after the other to explain the basic knowledge of satellite tv guide.

Satellite tv Guide: How does satellite tv work?

Programming Source

This is the contents of the service provider i.e the contents of the channels like HBO, ESPN, SuperSport, Signal-6, Sport 24HD and so on provided by the service provider like DSTV, TATA Sky, Skysport, Bein Media and So on.

These can be found on their respective satellite such as Eutelsat 36A for DSTV for sub-sahara Africa, Express AMU1 for Asian countries according to lyngsat and south-east Africa, Nilesat 7w For Bein Media, Amos 4w for Yes tv and so on.


DBS Provider Broadcast Center

This is the broadcasting center such as DSTV, TStv, AFA Sport, Champion tv, Multi tv, and so on. This Broadcasting center will collecting progamming source that’s collecting different signal from different source through their respective satellites and accumulate or modify it and rebroadcast the content through their center satellite.

For instance, DSTV or Multichoice receives signal from skysport for their live matches contents through the skysport satellite and modify it by branding, compressed and encrypt the signal before rebroadcast to their respective satellite.

And that’s the reason why Dstv or TATA Sky and other big digital tv service provider encrypt their channels because it cost them huge amount of money to have the rights to the live contents from skysport. To get their money back, the company needs to secure the channels to their subscribers only.

Space Satellite

Space Satellite used by DStv is Eutelsat 36B as stated above. TATA Sky used INSAT-4A and GSAT-10 satellite for digital compression and transmission of signal to the satellite. The satellite used by these company is geostationary. It fixed satellite to the earth and geostationary satellite operates as high as 35786km to the earth. The signal is received via strong transponder or frequency which will discuss later on.

Satellite Dish Antenna

The functions of satellite dish is to receive signal transmitted by the satellite as follows:

  • Through low noise broadcast frequency (LNBF) Mono plug
  • Owned and copyrighted of the service provider
  • Dish are available in different sizes
  • The longer the distance of the satellite the fastest and stronger the signal received by the viewers or subscribers.

Satellite TV Receiver

The satellite receiver is connected to the satellite dish via coaxial and cable connected to the LNBF on the satellite dish. And it then connect the satellite receiver to the tv via AV or HDMI Port. The main functions of the satellite receiver as following:

  1. To receive signal, decompress, decrypt, process
  2. And send the signal in form of digital to the tv. Example of Digital satellite receiver includes Dstv Decoder, Tiger T3000mega, Starsat Extreme receiver e.t.c
parabolic antenna

Satellite Tv Guide : Types of Satellite Dish

Satellite dish antenna are of two types which as follows:

  • Parabolic: The satellite dish antenna usually in curved shape like an egg of an ostrich i.e geo-speherical in shape and the second part is:
  • Feed horn: The signal received from the satellite are converge by the parabolic surface on to the feed horn. Note that the bigger the area of parabolic surface of your satellite dish antennae the higher the signal strength.

The Main functions of feed horn as you can see in the picture above are follows:

  1. Feed horn amplifies radio signal, the signal received from the high frequency is converted to low noise frequency and that’s why feed horn can be regarded as LNB (Low Noise Blockdown) converter.
  2. It send signal to the satellite receiver.
Satellite dish LNB

Satellite TV Guide: Types Of LNB (Low Noise Blockdown)

Normally, Satellite signal can be received via LNB in two ways which as follows:

  • C-band : The frequency/transponder of c-band usually in 4digits and the symbol rate usually between 4-5digit using wide band satellite dish antennae and by default LNB frequency is 5150
  • KU-band: The frequency/transponder of KU band use 5digits and symbol rate varies from 4-5digit and by default LNB frequency is 10900.

Here is the typical example of satellite dish commonly used for most of the installation across the world below:
