Ku Band Satellite LNB’s -how they work and Frequency Setting 

Great explanation. Ku Band (10.75 - 12.75 GHz) is the norm for satellite television (both free and paid) in Europe. We also have a saying that satellite television is the best alternative for both cable and OTA channels. C Band is used only for Russian TV channels on satellites Express AM7 40 East and Yamal 401 90 East. In Europe all the Ku Band LNBs available on the market are Universal considering that satellites broadcast on the full band. The Ku Band is 10.75 - 12.75 GHz is divided in two bands: the Low Band 10.75 to 11.75 (both Horizontal and Vertical) and High Band 11.75 - 12.75 GHz (H and V). When the receiver is set on Universal it scans all the available transponders, but if I install a C Band LNB I can change it in the settings. Also Universal LNBs have a 22KHz switch built in. In the sat receiver TVs with satellite tuner and digital meter the 22K Switch is set on Auto so the receiver can know when it's on Low Band or High Band. When the receiver uses Low Band then the 22K switch is off when the receiver uses High Band then the 22K switch is on. I see that North America uses the High Band for Ku Band (11.75 - 12.75 GHz). If we convert from GHz to MHz we have: 1.For Low band the input frequency is 10.75 - 11.75 GHz and the output is 950 - 1950 MHz 2.For High Band the input frequency is 11.75 - 12.75 GHz and the output frequency is 1.100 - 2.150 MHz Also the KU Band LNBs have 3G, 4G, LTE filter like OTA UHF antennas.

You have the perfect voice of Hashirama Senju, great video

I'm new to this, watched a few of your videos and also Robbie Strikes. I ordered the mini s2x 4k receiver that I saw you review. I'm starting to feel better about setting everything up. Thanks... Charles

I work in satellite communications. I’m very familiar with LNB’s. LNBs convert RF to L Band (950-1450 MHz). I test Ku and C band LNBs for functionality. Local oscillator for C Band in my field is typically 5,150.0 MHz and 10,750 MHz or 10,000 MHz for Ku. Basically you have to set your receiver to your Rx frequency minus the LO. So if downlink RF freq for Ku is 12,500 MHz, the in-house, L Band frequency is 1,750 MHz. I believe the reason why they’ve shifted for the most part to LNBs over LNAs is because L Band RF equipment (line drivers, fiber shelves, etc) is cheaper. Even though cheaper, equipment is still insanely expensive. An HPA, for example, which transmits an uplink signal, is over $100,000. Insane money. And redundancy is the name of the game in this field, so there are always backups in-line. 1:2 systems, basically 1 backup in the event the horizontal or vertical pol fails. Anyways, The in-house equipment the signal runs through at my job basically clears up and amplifies the signal so the customer is receiving the best downlink signal possible. It’s also worth noting that Ku band is more susceptible to loss due to weather such as rain, snow, high humidity and clouds (rain fade), so it’s not ideal for video as C Band’s wider, slower waves travel better across land, thus making it ideal for video. But most of the C Band bandwidth has been used up so other bands are being used nowadays. My company is responsible for almost all of the in-flight entertainment systems (movies, internet, etc.) in the USA. Basically our customers have their servers and RF equipment at our site. They use their servers to output internet, which is converted to L-band via their RF chassis, where it is then handed off to us and run through our RF equipment where it is conditioned/boosted and run to one of our antennas, which transmits whatever the user is requesting. It’s an interesting field that is ever-changing. We also track some of Elon Musk’s SpaceX satellites. I might also add that our teleport owns a massive terrestrial network. Internet connections from customer equipment to us are essential. From us, the internet runs on fiber out through redundant paths. Nice video!

Thanks COOP the WiSeNhEiMer from Richmond, INDIANA ...

Thankyou. For years I've been adjusting my dish and installing others for friends as well as well. Every once in a while an lnb malfunctions and I struggle through it I have a sat finder to help. Now I understand the process. Maybe you could do a segment on diseqc and how they work.

Thank for information

Great explanation of LNBs. Is there a way to determine what the focal point is of a dish? I picked up a used dish or free that measures 95 cm x 85 cm that had an LNB on it that I determined was a circular LNB (WNC Dual LNB-W) that was being used to receive DirectTV signals)so I purchased and installed a Linear LNB on it - the GT dual output LNB you showed in your video. So far I have not been able to pick up anything with it and was thinking perhaps I don’t have the LNB at the incorrect focal point

Hi Jeffrey, This is Joey and I'm new to fta. Just watch your video about LNB's. I got lost a little bit, you keep saying 97 w Gal 19 ku. Is that where I need to point my satellite disc let us say I would like to get a KU band. Do you have a video that shows how to point a satellite to get the KU band? Thanks in advance.

Do you like the GT LNBs? Where did you buy them from? Thanks

I just bought a Amiko Mini 4K.UHD S2X I have a 36" soild dish not getting anything? Any suggestions Thanks

Hi NH. I've got a 76cm ku dish. Seems to only pick up about a third of the stations on each bird I blind scan. Wondering if upgrading to a 99cm dish would help? Or maybe my focal point is off. Any suggestions?

Thank you for explaining Ku band LNBs. What is a god LNB for picking up weak satellites? Can you receive Eutelsat 115 West B at 114.9°W with the 3 foot Fortec Star dish?

Hi, I have an old Muzak brand dish. Their techs could not get a decent signal with their Super Buddy meter....one guy got an 8.5 out of it, but still won't register any signal on receiver? I mentioned skew, and they just look at me funny. Its a new Zinwell LNB and the thing is dead vertical....They used to have a skew chart posted but took it down. Are you aware of the angle for Kentucky for SES 3?? Any help appreciated

Which frequency is the best for lnb as far as free air channels go?

Got a dish and lnb to try. Satellite setup ís 107000 lnb Freq matches lnb sticker. In Australia trying Ku intelstat 19 that friend uses nearby but I can't get any signal. Stuck at 45pc intensity 10pc quality. Nothing changes as I rotate the dish around to try and grab a signal. I'm suspecting lnb must be bad as I confirmed settop box is good already . Anything else to check before I buy new lnb EDIT. Bought a new LNB that said on for ibtelsat19 and was 11300 Freq. And I'm picking up signal now. Just need to tune in channels and setup properly now. Seems like the 10700 lnb is no good for I telsat19.

Hello Robbie how can I get RU-vid on free satellite I have amino mini hd265 and free internet 😊

I thought you were going to tell how to check lnb focal point?

Answers some questions; the old dual Shaw LNB will work, but the newer triple satellite LNB will not (output freq of 950 - 2150 Mhz)
