- This is a video demonstration between the most common types of LNB's.
The LNB serves multiple function and is the part of the satellite dish in which the coaxial cable that feeds your TV is connected.
Once watching this video you should be able to tell the difference between the most common LNB types and identify the ones you're most likely to need for your own satellite system.
LNB's in the demonstration:
1x Universal LNB - 40mm collar size
1x Universal Quad LNB - 40mm collar size
1x Sky mini-dish Quad LNB - 38mm collar size
1x Sky mini-dish Octo LNB - 38mm collar size
1x Sky Q LNB
1x Quattro LNB (which connects to the multi-switch amplifier)
For more information on how to terminate a coaxial cable with a F connector which is required to connect to LNB's, watch this video:

Very useful video thank you
Hi, which would be the best LNB for my new 4K Freesat box? My old SKY + dish works, but I would like to upgrade it to a wide band LNB with 4 outlets. I will probably upgrade the mini dish to a 60cm one at the same time.
Nice one, cheers.
You're welcome John. Please do subscribe to our TH-cam channel.
We recently upgraded from a sky plus box to sky q, but as our dish is on the top of our roof, sky were unable to go to the dish to change the LNB for a sky q one, and our dish has 4 cables coming off it, so they installed a box in the loft, it has the 4 cables going in one side, 2 cables coming out the other. What exactly does this box do with the signal, and how does it work? Your video mentions something about a different mode for sky q? I'm now finally able to record sky programs, as the old sky box did not allow recording without a subscription (freesat) only.
Thanks you for sharing this fantastic reading and I appreciate it all okay 🥰🥰🥰
Thanks am watching you from Ghana, am so impress
Wow can't believe my videos have made it over there. Thanks for watching, please subscribe to our channel. Tom
Hi.
I had sky q installed, and when I did they made some changes to my dish (probably even changed the whole dish), I am thinking of replacing the LNB on it to a hybrid one so that I can run 2 other cables to my other room for free sat whilst maintaining the sky q connection in another room. Have you done a video where you have changed the LNB on a sky q dish? Is it the same procedure for all dishes?
Sorry no video at the moment. I will do one though! Yes you want to purchase a Hybrid LNB and install onto your existing dish. This is a simple job, only needs a small headed screwdriver. Providing you can get access to the satellite dish that is. Tom
Hi man could you tell what is Best LNB for Hotbird satellite also 4k channels also suitable for UK weather
Thanks in advance
Thanks very interesting 👍👍👍
You're welcome Dan, please subscribe to our channel. Tom
I wonder how a quatrro lnb works. Do we need to supply voltage to each of the four output or just any one of them so it will work?
Trust Sky to make things complicated. I'm sticking to everything free to air. Thanks for the great videos
I know, they are sods. Thanks, please subscribe to our channel. Tom
I have a smart LG tv which has a sky /cable port connection but my old sky don’t work in it what lnb would I need to get
I have a lnb with 4 connectors on, just got thefreesat re ordable 4k tv box,its all working fine, but I want to put another cable in as the box takes 2 cables, but one of the connectors is stuck and wont come off,I can not use the other 2 connectors as they go to other rooms,I will try and get the connector off, but if I can not,I will replace the LNB of the same
Hi Tom, I want to split satellite signals for 4 combined satellites in 20 rooms. How can i do that?
does the sky2 lnb work with standard sky oval dish? just exchange it with old sky lnb?
With the oct, can I have 2 sky Q boxes and 2 normal HD boxs working from the same llb
Please sir how can one use lnb with 4 outlet to different frequencies
Hi Tom Can you tell me if it matters which way you put the f connectors on the back of a sky q box?
Hi David, no it doesn't matter which way around you connect the satellite inputs.
Please do practical section for us to understand it well!.
Hi Tom
Thanks for the very helpful video
I live in Guernsey where we have access to the same services as in the UK mostly.
I have a network 4 tuner satellite receiver which works with Plex Server for recording and 9 TVs around the house. From watching your video I know that I need a quattro LNB & a 16 channel multiswitch. The longest run of cable would be less than 30m. I expect the cost of installation will far outweigh the cost of the kit so I'd prefer not to compromise on quality. Are there LNBs & Multiswitches that you'd recommend & could you ship them to Guernsey?
I forgot to ask......
Given the proximity of the sea, I'd like to have a fibreglass dish - what type/size/manufacturer would you recommend?
Hi Martin, sorry we don't sell the kit. I like Vision products so I would recommend their multi-switches and LNB's.
Depends on the satellite, but for English TV and your set up and Triax 65cm fibreglass dish would do the trick.
@@smartaerials9718 Hi Tom, That's really helpful. Many thanks, Martin

Question from someone who knows nothing about satellites,;
I have one to I want to watch freesat on. I'm not interested in recording programs. I have a quad LNB.
Am I just using a single coax cable?
Sounds stupid but are double coax for recording and/or more than one tv? Thanks 🤘
You don't know nothing about satellites because you are absolutely correct! Single coax is fine for what you want to do.
Smart Aerials thanks so much!!! I've spent ages flummoxed about this until it dawned on me that my freesat box only had one input! I'm one lunch break away from getting wired up.
Absolutely love your channel by the way. Cheers again 🤘
Might be a silly question,but i have a 4 LNB on a dish to rrun an old Sky box in my garage,but the white plastic capping has fell apart and fell off,what can i do to repairr it,can i get a new cover or can i just use Clingfilm to seal the end?cheers!!!
Hi Gordon, I would just get a new LNB to be honest. They are relatively inexpensive when buying online. Sounds like you need a Sky Quad LNB.
So with a 5 in (1 terrestrial) 8 out triax switch coupled with a quattro I can watch 8 different channels on 8 different sky boxes?
Yes that's correct. You may want to install a 16 way switch instead and 2 cables to each room so you can connect Sky+, Freesat+, satellite PVR boxes.
Hi Tom
I’m pulling my hair out at the moment. I’ve refurbed my house with new cables and equipment, quad LNB feeds a triax 16 way multi switch picking up 8 shielded wall plates with two cables apiece. When I plug in my humax freesat pvr into one room I get 100% strength and 90% quality signal. If I move the freesat box to any another room I get no signal found. Am I missing something obvious?
These quad lmb ,I would run 4 cables to my two receivers that have two tuners in each reviecers ,Freesat Humax pvr?
Hi Stephen, yes a Quad LNB would be fine.
I HAVE A 60CM DISH CAN I TAKE THE LNB OFF THAT ONE AND CONNECT IT TO A 120CM DISH AND STILL COLLECT ALL AVAILABLE SATELLITES THANKS
Hi Tom. Can you tell me the maximum length the cable from the dish to Sky Q receiver can be?
if you use quality cable (copper) easily 100 meters
Is the Quattro the same as unicable? My LGTV has one satellite input but an option in the menu for unicable. Does this mean I can watch and record at the same time and if so, which lnb would I buy, ideally to fit a sky minidish?
Hi there, no it's not the same. We don't really use unicable in the UK (if that's where you are?). Usually to record you will need to connect a USB hard disc drive. If you have done this I advise setting the LNB setting to 'unviversal' on your LGTV. I hope this helps. Tom
@@smartaerials9718 thanks for coming back. I am in the UK and have a standard quad lnb with Freesat and works fine and records fine but only while watching same channel (single cable input on the LG).
I was just curious of the unicable option in the LG TV satellite menu and I recall the spec said twin sat tuner when I bought the TV, so I imagine they mean with unicable, as there's only one input.
I only really use record function on this TV to pause and rewind live TV so I'm not too bothered, just like to play with all the available technology!
@@RandomShart In a Unicable or Unicable II / JESS there are small receivers, which receive the transponder and put it on another frequency over one coax for more satellite receivers.
These are fixed frequencies, the receiver must then support unicable.
For example
1210 Mhz
1420 Mhz
1680 Mhz
2040 Mhz
I am a bit late in replying. There are two different types of Unicable/Wideband LNBs. Lo 10.40 and Lo 10.41. UK Sky Q/Freesat 4K uses the Lo 10.41 Wideband LNBs. Europe uses Lo 10.40 Wideband LNBs. A European Wideband LNB will not work on a UK Sky Q/Freesat 4K receiver. If you are just planning to watch FTA and not get Sky then either Wideband LNB type is good to go. A Unicable 10.40 LNB will not work with a Sky Q/Freesat 4K receiver. You need a 10.41 Unicable or similar LNB. These LNBs with the exception of Sky Q LNBs won't fit a Sky Minidish(without an adapter).
@@mebo870 Linux based receivers such as Vu+ Duo 4K with a satellite card installed will work fine with an Unicable LNB/Unicable multiswitch. You won't be able to watch encrypted Sky channels though.
I’m a it confused by how to connect a dish up to two receivers with two tuners in each ,do I use 4 runs of cable with a quad lmb one the dish ?one cable for each tuner ,or can I use two splitters and two runs of cable of each spitter ,using only two main cables to the dish what’s the best way to install a single dish to two receivers pvr Humax free sat ?
Hi Stephen. No you can't use splitters I'm afraid. You can find more info here: www.smartaerials.co.uk/blog/why-cant-you-split-a-satellite-signal-cable
Install a Quad LNB and run two separate cables to each PVR. (4 total)
Is there good quality LNB and bad LNB in market or all the same?
There are all sorts, the better ones have a lower noise figure. Some are high gain but these are only really suitable for long cable runs. To be honest most LNB's are pretty good now,
Hi tom .getting fed up with sky charging a fortune so bought myself a humax freesat box ..but my sky q cables 2 off .i put one into humax and no signal .do i need to change Lnb .cheers
Hi Gary, with it being 4 months later I hope you fixed it but I have just had to to do this.
We have a quad LNB on our static caravan. i have tried connecting our Sky Q box, however a signal cant be found. Do i need a Sky Q LNB
Yes because the Sky Q LNB is a wideband lnb, whereby the high and low bands are received together.
I have a quad lnb with no connection numbers and not in a line does it matter what wires i connect to which connections.it,s sort of a square box with spaced connections?
No it doesn't matter, on a Quad all the outputs on the LNB are identical.
will the signal be weaker if split by four or eight outputs of the lnb?
Hi Joe, no it will be fine. Tom
@@smartaerials9718 you cannot split a lnb output, there can only be one master. What will happen when 2 receivers are on a lnb, one asks the high band, the other the low band = problem.
The second receiver can hitchhike on the selected band (1/4).
Oh my days thank you. Just ditched sky and the satellite would not tune(other than itv) and I have been going insane as it has worked at our old house. Best get LNB shopping then. 👍
Right now, Which make of LNB Gets the Strongest signal ,out of all LNBS
the last Quad LNB, can that be used with sky Q too?
Sky Q will only work with a wideband LNB or a Hybrid LNB(This is a wideband + Quad LNB). I hope this helps. Tom
I love your vid but while i thought you'd had elaborate more on the multiswitch as it seemed a vague. From Ghana West Africa
Hi and thanks. I will make a separate video on multi-switch amplifiers. All the best. Tom
Do you use a F connector to connect to a LNB? Many thanks
Yes F connectors, just make sure you get the correct size.
@@smartaerials9718 Thanks👍
Would a round dish still receive sky channels? Thanks
Yes round dish will still be fine, should be at least 45cm, 60cm up North,
Smart Aerials thanks mate
Super but these all we cant get in indian market
kindly plz if u don't feel, i have a suggestion some time language is very speed so kindly plz slow...
Now i sub u r channel... Very good super vedio
Hi and thanks. Yes I always speak too fast. I will try to slow down in future. Tom
Can you not use the youtube cog icon and set the speed to one you're happy with?
For the quad, does that mean I can watch different channels from different TVs at the same time?
Sorry I do not understand, for the quesd?
.. quad
@@jaysonsreview Yes you can watch separate channels with a Quad, but you would need separate satellite receivers at the TV's though.
@Smart Aerials Great! Because I bought an X2 Universal LNB, and I was wondering what's the purpose of the other output. Thanks for clarifying!
@@jaysonsreview You're welcome, glad to help. Please subscribe to our channel. Tom
My question is the lnb skew numbers, how do you count the + or -
Hi Ty, it's done in degrees. If your LNB has numbers I would check with the manufacture literature to see what this corresponds to. I hope this helps. Tom
I need to replace the white plastic part of the LNB on a sky/freesat mini dish. I think my LNB has got rain in it. I don't need the whole bracket, just the plastic disc bit. Looks like I can buy one for about £3 online. Are they easy to remove and replace?
I think that you are referring to the plastic cover on the feedhorn. I don't know I have never done it myself.
@@smartaerials9718 I expressed myself badly. I see LNB replacements on sale which include the arm. I don't need the arm, just the LNB (for Freesat). Are they easy to remove & replace? The dish has been up since I moved in in 2011. I presume that means it's a MK3?
Oh Ok, Yes they are easy to replace, should just be a case of unscrewing the old LNB and putting the new one in but you have to make sure that you set the skew correct. Most LNB's for Sky have a collar size of 38mm but some of the new ones are 40mm though so you may need an adpater. I advise just ordering the new LNB and seeing if it fits.
Question mate. I just recently used a company was having issues with getting signal. I hVe Sky Hd box. 3 different rooms. Fella came in che ked the signal on hjs machjnes. Said most likely LNB has gone. Ofcourse i need a LNB Octo. Call out charge was £72. Didnt mind that as they came withjng couple of hours. HOWEVER (bearing in mind i was talking to the geezer for about an hour seemed like a decent nloke) charged me £153 for an LNB so all in all i paid 225.
Today (2 days later) i checked online the most expensive LNB Octo is about £30 that i can find. Have i just been done for???? Also what can i do about it?
It does seem expensive to me for the part, but I advise that you check with installer about the price. There may be a legitimate reason or may have just sent the wrong amount by accident. It's common to mark up parts in our trade as there is a lot of dead time travelling between jobs. But £153 just for an Octo is very expensive.
As a canadian, I cant understand most of what you're saying. Talk slower or add CC please.
