Chech the following out about LNB Satellite dish LNB help What's the Best LNB? Oval or round? What LNB do I need for HD/SD? What LNB do I need for DiSEqC? Can I split the feed from one LNB to two tuners? Universal LNB Twin-output LNB Dual or Monobloc LNB Quad-output LNB OCTO 8-output LNB Quattro LNB What is an LNB? Low Noise Block-downconverter (so called because it converts a whole band or "block" of frequencies to a lower band). Also incorrectly known as a "Low Noise Block" or a "Low Noise Blocker"! An LNB sits on the end of an arm and faces the parabolic reflector ("dish" which focusses the signals from a satellite 24,000 miles away into the "feed horn" of the LNB (see pictures below).The LNB converts the signals to a lower frequency and sends them out to the cable connector, which you connect to your satellite receiver via coaxial cable. What is an LNBF? This is the term for an LNB with an integral feed horn. Nowadays the "F" tends to be omitted. What is an LNC? Low Noise Converter. Basically the same thing. A modern "universal" LNB is able to operate in four modes to provide signals from four frequency bands, known as "low-horizontal", "high-horizontal", "low-vertical" and "high-vertical". An LNB may have more than one output but any one output can provide only ONE of these bands at a time. In order to tell the LNB output which of the four frequency bands it needs to provide, the receiver "communicates" with the LNB as follows (this gets technical):- A modern "Universal" LNB requires a 22 kHz signal at 0.5v p-p to switch its Local Oscillator to 10.6 GHz ("high band" . Otherwise it uses its 9.75 GHz oscillator.Polarisation switching is controlled by DC voltage supplied by the receiver. 12.5v to 14.5v gives vertical and 15.5 to 18v gives horizontal polarisation. A higher voltage than that can damage the LNB. A voltage that is too low will prevent the LNB from working correctly. Under normal circumstances, one cable can carry only one LNB feed (because of the voltage and tone communication method), although it is sometimes possible to use a "stacker-destacker" to carry two. What's the Best LNB? We try to stock the "best" available. For example, the "Invacom quad" has the best cross-modulation performance of all the LNBs I've had tested. In layman's terms, this means that a weak transmission on one polarisation is less likely to be drowned out by an adjacent strong signal on the opposite polarisation. This parameter will be of interest ONLY for a dish of 2m diameter or larger. On an 80 cm dish you might as well use the cheapest LNB you can find because it won't be able to collect a strong enough signal to cause this cross-modulation problem. As another example, the (obsolete) Thomson Sky LNB was said to have a higher gain than usual. (This is hearsay - I never had it measured). The result was (allegedly) that it could be used with a longer length of cable BUT, some receiver tuners got overloaded if it was used with a short length of cable. So you might say that this LNB would "perform better" with a long cable run (but it might be crap with a short length). An important point to recognise is that an LNB will work at its best when it matches the dish. This means that an LNB which is designed to focus on a dish which is circular (when viewed from the LNB position) will not give its best if you fit it to a dish that is wider than its height - and vice-versa. In addition, the LNB must be fitted so that it sits at the exact focal point. A couple of millimetres either way will reduce the amount of signal and increase the amount of interference. The LNB "skew" (rotational position) must also be correct, otherwise signals of opposing polarisation will interfere with each other. Assuming that you've chosen the correct type of LNB and got the adjustments right, it's unlikely that you'll benefit from changing it for a different make of LNB. You'll see all sorts of silly claims such as "0.2 dB noise figure". Believe me when I tell you that any noise figure below 0.9 dB is fine. You won't see any difference whatsoever - even if the claimed noise figure is correct. Dish size is what matters, and dish quality. There are some dishes on sale which are flimsy and poorly made. We don't stock these. If you buy on price alone, be prepared for disappointment and bear in mind that it's much easier to swap an LNB than a dish. If you swap an LNB and see an improvement, it's likely that the first LNB was OK but was designed for another dish and probably didn't have the range of adjustment required to set it at the exact focal point. However, LNBs can and do fail so don't discount the LNB when you look for fault causes. Note: we stock LNBs for Sky dishes and LNBs for "circular" dishes. Do not mix the two. As far as we can tell, the LNBs that we supply match their respective dishes adequately, so there's no point asking us about this before purchase. However, if you find a problem after purchase, we do want to hear about it. How to test an LNB? I think my LNB is faulty. How can I test it? The only way to fully test an LNB is to fit it to a suitably aligned dish and connect a satellite receiver. Then check to make sure every channel is there. If no channels are missing and if it continues to work through a hot day and a cold night, the LNB is fine. However, if some channels still appear to be missing (with a known good LNB), this could be the fault of the cable (bad connection, water ingress or kinked or wrong type), the receiver or the dish (distorted or misaligned) or local interference (DECT phone, car radar detector, etc.). So then you need to use a process of elimination by swapping the dish, the cable and the receiver (for a different make/model as some receivers won't work correctly with some LNBs). Note that some wall-plate connectors can also cause "channels missing" problems and some electronic devices (DECT 'phone base stations, "Snooper" type radar detectors and microwave ovens) can cause similar problems. I've even had it reported that a bad battery connection in a laptop computer wiped out some channels! Can't I test it with a meter? A cheap Satfinder meter simply looks at the average strength of all frequencies. It will not tell you if some frequencies are missing. An expensive meter looks at a specific frequency (sometimes more than one) but it will not tell you if some frequencies are missing. Also, most meters rely on battery power. If the battery can not supply enough current to the LNB, it may give a false reading. What LNB do I need for HD/SD? All modern receivers use a "universal" LNB which is compatible with all signals. Make sure that the LNB you choose has sufficient outputs for your receiver(s) which will have one or two inputs each. You can not "split" the LNB cable because each receiver input controls its own LNB output exclusively. What LNB do I need for DiSEqC? DiSEqC is a signalling protocol used by some receivers (not Sky) to control an LNB switch or a dish positioner. It is also used by some LNBs which have a built-in DiSEqC switch. This type of LNB is called a "Monobloc" or "Dual-horn" LNB. Can I split the feed from one LNB to two tuners? Yes but it won't work properly. You should fit an LNB with more outputs. List of Universal LNB types: The term "universal" is used to describe an LNB that has "dual band" tuning capability. It came after the "enhanced" LNB which had a slightly extended tuning range and used a 9.75 GHz oscillator instead of 10.0 GHz. Some people mistakenly think that "universal" refers to "universal fitting", meaning the LNB will fit any dish. There is no such LNB. It's important to choose an LNB which is suitable for your dish and matches your receiver. (All modern "digital" receivers in the UK will work with a "universal" LNB. The same is NOT true for the USA.) A Universal LNB requires a 22 kHz signal at 0.5v p-p to switch its Local Oscillator to 10.6 GHz ("high band" . Otherwise it uses its 9.75 GHz oscillator ("low band" . Used by ALL modern satellite receivers for Sky, Freesat, FTV and FTA viewing.Polarisation switching is controlled by dc voltage supplied by the receiver. 12.5v to 14.5v gives vertical and 15.0 to 18v gives horizontal polarisation. A higher voltage than that may damage the LNB but most are OK up to 20v. A voltage that is too low (less than 12.5v) will prevent the LNB from working correctly. Single-Output universal LNBs Note: single-output LNBs are seldom used nowadays unless you have a specific reason - such as squeezing several LNBs together on one dish. Most people keep their options open by fitting at least a quad-output LNB, which provides four separate feeds for (say) four satellite TV receivers or two Sky+ or HD PVRs. (You can't split an LNB feed so be sure to install an LNB with as many outputs as you are likely to need in the future.) Typical single-output "Universal" LNB 9.75 and 10.60 GHz L.O. The (obsolete) Cambridge "Platinum" Geo Universal G57" LNB Works in 2 bands* 10.7-11.8 and 11.6 - 12.7 GHz. (22 kHz signal switched). Noise Figure usually 1.0 dB or better. Integral feed horn with 40 mm neck but C120 flange type available in some models. Spigot fitting for Sky Minidishes. "Twin-output" universal LNB Previously available in Standard (10.0 GHz) and Enhanced (9.75 GHz) form, but now only in "Universal" form (9.75 + 10.6 GHz), the twin-output LNB provides two outputs to feed two separate receivers for independent working. Each output can be switched independently by 13/17 volt input by the individual receiver to change polarisation and by 22 kHz to change the band. This type of LNB is sometimes offered with an adapter to fit it to an oval Sky minidish. Beware! It is not designed to focus on an oval dish so its performance when the signal is compromised by bad weather will not be optimal. "Dual LNB" or "Monobloc LNB" Comprises two universal LNBs fixed together at a small angle in a single housing. Only one "F" connector is used. A single coaxial cable connects to the Digital (or Digital + Analogue) receiver which must be able to use DiSEqC signalling to select which LNB is to be used. Normally used on an 80 cm dish to receive Astra at 19.2'E and Hotbird at 13'E (but not simultaneously). Monobloc set-up Monobloc setting up This type of LNB has a single output and the actual satellite signal is selected by the receiver which sends a DiSEqC (22 kHz) pulsed tone up the LNB cable. So only one satellite transmission can be viewed at a time. This is in contrast with dish systems that have two or more separate LNBs where, with two receivers, both satellite transmissions can be viewed or recorded simultaneously. See picture HERE. Not compatible with a Sky Digibox. Not usually suitable for fitting to a Sky minidish (although it can be done - but expect poor performance in bad weather). "Quad-output" or "Quad universal" LNB This universal LNB can feed four separate receivers. Each receiver has independent control of polarisation and band via 13/17v switching and 22 kHz o/off respectively. This LNB is used with the new Sky Digiboxes and Freesat receivers that have two LNB inputs and internal Hard Drives for recording a programme while you watch another. Two LNB outputs go to this "Sky Plus" Digibox (or Freesat+) and the other two LNB outputs can go either to two standard Digiboxes or to one other "Sky Plus" (or Freesat+) Digibox. As illustrated, this LNB is not suitable for use with a Sky minidish. The Sky minidish version has a spigot fixing. "OCTO" universal LNB As above but with eight independent outputs. We stock a Sky minidish "spigot" version and a standard (40 mm neck) version. The latter works well with a 60 cm dish in the UK. "Quattro" universal LNB This has four fixed outputs and is used only in "head end" I.F. distribution systems (or "multiswitch" for apartment blocks. One LNB supplies a head end unit that can provide (typically) up to 16 outputs for separate Digiboxes. The four outputs of the LNB are as follows:-1. Horizontal polarisation low band 2. Horizontal polarisation high band 3. Vertical polarisation low band 4. Vertical polarisation high band You should not connect any of the Quattro outputs, 1 - 4, directly to a receiver (except for testing purposes) unless you want to restrict viewing to just one of the four band options. Even if you do, the receiver may not work. If you simply need four or eight outputs, use the Quad or OCTO instead. No Quattro is manufactured to fit a Sky minidish. It always requires a (roughly) circular dish. Click HERE to see a suitable dish for England. How do I get more than 8 LNB outputs? Connect a QUATTRO LNB to a MULTISWITCH If you "mix 'n' match" by picking a 60 cm dish and a Universal LNB at random, the chances are that the performance could be no better than that of the Sky minidish. As a general rule, any standard LNB will work with a circular (prime focus) dish or an offset focus dish which is taller than it is wide (which "looks" circular when viewed by the LNB). There are some exceptions: a dish optimised to hold more than one LNB may be an "odd" shape. Some dishes are oddly shaped for mainly aesthetic purposes. However, a dish which is considerably wider than it is tall (as viewed by the LNB) will need a special LNB for optimum performance. Just to prove the point, here is a very early type of "Universal" LNB used with a Sky "minidish" (no longer manufactured). The minidish is oval in shape, being much wider than it is high. Inside that plastic rain cover is the actual LNB. Note the difference in scalar ring height (red arrows). The side projections allow the LNB to focus on a wide area in the horizontal plane, while the top and bottom projections are longer and focus the LNB on a narrower area in the vertical plane. This LNB is designed specifically for an oval dish and will give very poor results with a dish that is roughly circular or a dish that is taller than it is wide. ere's another comparison. The SX1019 on the left has circular scalar rings inside the feed horn. It is designed to be used with a nearly circular dish. The SX1019/S on the right is designed specifically for a Sky minidish which is wider than its height. This type of LNB can also be used with a Raven dish of a similar shape to the Sky minidish. Both LNBs are made by Philips. The one on the right, however, is branded "Skyware". Sky "Minidish" upgrades Here is an obsolete Philips SC519QS/S Quad output LNB, which used to be supplied with the SKY-plus system with adapters for the "minidish". The red arrow points to the special oval shaped "scalar" steps in the feed horn. These cause the LNB to focus exactly on the oval shape of the "minidish", using the full dish area but without picking up reflections from the wall behind. This type of LNB would not give good results with a circular dish. Some dealers are offering a standard Twin-output or Quad output LNB with an adapter to fit the "minidish". The adapter fits a treat. Unfortunately, the LNB will not give optimum performance - and could give "rain dropout" during bad weather. (We can supply an adapter to fit a 40 mm LNB to a Sky minidish but you use it at your own risk). However, you may prefer to buy a standard dish of, say, 60 cm diameter and use a standard 40 mm neck twin-output or quad-output LNB with this. The match and fitting will be perfect and the "rain dropout" will be very rare. If you are fitting a Quad-output or OCTO LNB to your dish, read this page. The LNB, above, has a spigot which fits into the Sky minidish arm. The LNB rotational position or "skew" can be adjusted by slackening the two screws that secure the spigot and twisting the LNB until best signal quality is achieved. The LNB on the left has a single screw but the principle is the same. A Sky LNB will often have graduated marks from 1 to 5 as a guide to alignment. Start at 3 and twist each way to locate the best position. Remain blessed. |
loluc90:I reside in Abuja, I got my LNB from the Plaza behind the Neighbourhood, Area 3, Abuja. Remain blessed |
ftadream:Thanks, Yes, my signal strength I ave been able to get it increased which allowed another frequency to pop up; 12054v27500. I therefore han an increase of channels from 46 channels to 63 channels. The signal of the tracking frequency 12075 v 27500 (with LNB at 8 0 clock) or 12075 h 27500 (with LNB at 5 o clock) increased from 54/55 to 56/57. I am still working on it. I promise to post the detail of my outcome. I vae started my experiment on DSTV 90cm as well. The outcome of my result shall immediate posted at the conclusion. |
I Hacked:Thanks form your question and commendation. I tracked Nilesat with the next dish to DSTV 90cm dish, that is 100cm = 1m dish size. remain blessd |
My people, I told you I am looking for a powerful LNB I can use to continue my tracking. I just returned to the office with one now. I wish to share this for any one who can lay their hand on it. It is very expensive but, the outcome of my research over the weekend will enable me share more of my findings. Here is the picture below and wish me good luck.

With inverto black quad LNB, you will all be able to track Nilesat easily and with good signal quality, but getting the LNB in our macket here in Nigeria proof a big proble. Anyone with information on how we can get it here in Nigeria? remain blessed. |
Please, does anyone hear about this ES 21 LNB or ES 51 LNB, I have been trying to get one but uanble. This another set of LNBs described as been very good. If anyone have information of how I can get it, hit me through my email:petfuntech2010@gmail.com. Remain blessed. |
Back to my discussion again, The MBC HD channels can be received only with Technosat T786 decoder, the package is free once you purchase the decoder for 560 to 600 UAE Dirham. it does not come on other HD receivers except Technosat T786. Check this link for more info: www.mbc.net/hd |
D.lee:I remember mentioning here that the era of using Strong decoder to watch DSTV is over, since DSTV has identified a way of shooting your decoder down off their signal. A friend of mine showed me text message from dstv, in the message, he was told clearly that if he is no longer able to watch SS3 and other vital channels, this means he is not using DSTV decoder, he should therefore go and get DSTV decoder. This is an indication that, once you are not using DSTV decoder to watch DSTV before, get ready to get one, you will no longer be able to watch DSTV channel again without DSTV decoder. What a cunning way of making money? e e e e e e e e e e e e D, S, T, V. |
ftadream:I promise to work on the Spit fire and give the house feed back. But from my latest findings, I have the following information on Nilesa.;There are three (3) main Nilesat as mentioned below In real time the Nilesat satellites are not exactly on same longitude ( Orbital position ). Eg via tracking on http://www.n2yo.com/?s=36830|25311|26470|33750 Nlesat 201 is @ -6.98 longitude Nilesat 101 is @ -6.86 longitude Nilesat 102 is @ -6.96 longitude While Atlantic bird 4A ( Nilesat 104 ) is @ -7.3 longitude The image below shows the current longitude position of the individual Nilesat satellites. Nilesat 201 is closets to Nilesat 102. http://farm7.static.flickr.com/6016/5884629848_b012da42d5_z.jpg The lines drawn around the satellites indicates the orbits on which the individual satellite travel on. Please note that satellite are constantly moving around their orbital locations. In Summary, Use Nilesat 102 for tracking Nilesat 201 as it is the closest satellite. For tracking Nilesat 201 use frequency 11958 H 27500 Fec 3/4. Earlier frequency 11727 H 27500 was the best frequency to track Nilesat 201 in Fringe reception areas but since the changed Fec on the frequency from 3/4 to 5/6, the signal became illusive in fringe regions. For you to watch MBC HD, you will need their decoder. The channels are actually free, but on other receivers, scrambled, but on their own decoder, free to air. Technosat T786 decoder is for MBC receivers. |
jayboskie7:cHECK YOUR SIGNAL ON THIS FREQUENCY: 12207h27500, ALLOW YOUR lnb TUNED TO 5O clock for you to have signal up to 54% to 55%, then blind search your decoder, I am very sure, your are goog to go. Remain blessed. ftadream:I promise to feed you with the details of my finding as well as the pictures. |
Like I mentioned before, I tried 4 different LNB, PRime focus, Fuji, Premium 2 HD and Premium Super HD LNB. The result is here below by using 12207H27500 as primary frequency; 1. Prime focus did not give me any signal. 2. Fuji LNB gave me the signal up to 50% 3. Premium 2 HD gave a signal up to 53% to 54% (fluctuating) 4. Premium Super HD gave me up btw 54% to 55% (Fluctuating as well). There is another LNB I used as well which give me signal up to 51%. I am presently using the premium Super HD. I am presently watching 47 channels free including all MBC channels. I av 6 JSC Sports ( JSC sports 1, 2, +1, +2, +3,+4 and Global Sport) including AD Sport TV and two extra sports stations. I am still working on 11958V27500 where we av other JSC sport +5 to +11. By the grace of God, I shall record success. I promise to furnish you with more details, because I am still working on it to see how I can boost the signal, if at all there is any other better LNB. I am still checking the market. Once I av my break through, I will commence my research on 90cm. If anyone wants to try it, do so with either Premium 2HD or Premium Super HD, but rather the latter. U can use DAAR SAT Dish , because it is also the same type of dish size with what I am using. I promise you all more information. The only thing is get the time over the weekend. Remain blessed. |
D.lee:The signal strength of the PREMIUM SUPER HD LNB is better than FUJI. I tried the two but I rather ask you to use the Premium. You can see the pictures attached. figment232:I bought the LNB here in Abuja @ 1,500. lovala:Since your friend is here in Abuja it is very easy for him to get it. I bought my own at Neighborhood Plaza. Remain blessed

ftadream:You got it, but there are two types of that LNB, there is one PREMIUM HD and another one PREMIUM 2 HD. The one I used is PREMIUM 2 HD. I will try to load the picture in my next posting later and the picture of the Dish. Remain blessed |
The signal quality of 12207H27500 fluctuate between 54% and 55%. Remain blessed |
D.lee:You are right my brother, I could not believe it myself that I can track Nilesat with 1M dish size. I have been looking for this dish for a very long time for me to give a trial. I really believe that what is not possible can be made impossible, all we need is put in more and better efforts than before. We begin to fail when we are not ready to take risk, devote time and resources. I am still pressing more to see if there is another better LNB than Premium HD LNB that can do the magic of tracking Eurobird and others. FTA has com to stay and shall remain. Remain blessed. |
I am very sorry for the picture quality. |
Here are the other pictures
|
I hereby attach the pictures of channels I got and I promise to post the picture for the dish. I snap the pics with my phone yesterday night, there is no way I could get that of the dish very clear.

HD PREMIUM 2 cost me 1,500 @ Neighbourhood Plaza, here in Abuja. |
I tracked Nilesat with 1m dish. The next to DSTV 90cm dish size, the type My TV were first using. |
I reside in Abuja. I tried 4 different LNB. 1. Prime focus, I was told this is the ideal LNB for tracking Nilesat, but I could not succeeded with that. 2. I went on using Supermax as a trial but failed, 3. [/b]I decided to use [b]HD PREMIUN 2 LNB, this was the LNB that got me the tracking frequency 12207H275499 up to 55%. Then I blind search to get others. 4. Fuji LNB also tracked it but HD PREMIUM gave me the best satisfaction. Remain blessed |

My people in the house, I can not believed this, that I was able to track NileSat with 1m dish over the weekend. Since saturday, I av been watching the following channels; MBC1, MBC2, MBC3, MBC4, MBC DRAMA, MBC ACTION, MBC MAX, AD DRAMA, ZEE AFAM using this freq. 11938H27500 Also, JSC SPORTS 1, JSC SPORTS2, JSC SPORT +1, +2, +3, +4 AND GLOBAL SPORTS using 12130H27499 AD Sport TV, CITRUS TV etc. Remain blessed in the house. |
Everyone in the house, DSTV has come again, the reason why many can not watch SS3 and some other vital channes of DSTV on Strong Decoder anymore is because, DSTV has taken steps blocking their channel on strong decoder. I could not beleive it until my friend in the office showed me text message from DSTV. The message said, if he can no longer watch ss3 and other vital channel, let him go and get DSTV box because he did not have one. DSTV has come with their new plan. if any one have the intension of going for DSTV old smart card, it is adviceable you suspend that now. God bless you all. |
good day to all of you. i wanna ask where can i find the latest software for Mediacom Excel great. I did not wish to bring this up here, but for over 6 months I have been searching for the firmware to upgrade my own. The decoder is a free to air decoder but very powerful. There are some channels this decoder can track and Strong can not track it. But the only problem I have with it now is the Audio. I need to upgrade it either to the last software released or new software. Please, God will bless you all as you considered my apology and acceptance to help me out. Remain blessed. thanks |
jossybless:NTA always show it. Remain blessed. |
D.lee:The sat was launched almost 3 months ago, they are now on test transmission. The sat covers the whole of Nigeria. I am 100% very sure more channels will trooping in very soon. They have problem presently with their C-band. The goodies will be very great. Let us wait and see what will happen. Stay bleesed. |
Lanceosas:I did the experiment with Strong Dish 65cm and I succeded but I am presently using DSTV dish 90cm. remain blessed. |
Sorry, this is the clarification 1. First track w4/w7 using 12437H23437 btw 65 - 75%, then tight the dish. insert this frequency 10975H29998. Raise your dish a little bit up, u will hit green (make sure u hit 85% to 89%, that is New dawn (32.8degree east) for you. That is also your primary focus, tight your dish completely. 2. Take another LNB, place it directly on top of the new dawn, use this frequency: 12437H23437, twist the LNB to almost 9am facing the dish, u will hit green, adjust the LNB ti hit btw 60% and 68%. First use a good tape to hold them very tight. That w3/w7 for u. 3. Take the 3rd LNB, place it direct under New dawn, twist to almost 3pm clockwisely, use this freq: 12551H19531 or 12543V20800, start moving the LNB swinging it to the Right and left until u hit green. It is very easy. Remember that, u only track w4/w7 first 4 u to track New dawn. Remain blessed. |
I succeeded in tracking 3 sat 1. New dawn at 32.8e using 10975H29998 - 89%,just a little above w4/w7 at 36e- this is the primary, 2. w4/w7 at 36e using 12437H23437 - 62% directly on top of New dawn. With this 12092 H 27500 pop to 98% and 3. MultiTv at 28.2e using any of the two transpoders - 65% (it can increase than that but that this is enoigh for me) just 5 to 7 inches under New Dawn (right hand side) All the channels pop up very strong. Yo can all try it. Thanks for the information Iron2011. |
which focusses the signals from a satellite 24,000 miles away into the "feed horn" of the LNB (see pictures below).
