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.

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!

[@NorthcoasterHobby]

I enjoyed reading your comment; what an interesting field to be able to work in, sounds like a very cool job to have! Thanks for sharing this information. It seems like simple math the way an LNB mixing frequency gets subtracted from a broadcast frequency to make the signal suitable for travelling through coaxial cable, but those little LNB’s have some magic inside of them.😄Feel free to visit my channel anytime, thanks for watching!

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

[@NorthcoasterHobby]

Great to hear, it’s a learning curve, indeed, but definitely worth it. Thanks again for watching!

[@yakovdavidovich7943]

The "conditioning" and "magic" are the down-conversion function of the LNB. The LO is mixed with signals coming into the antenna, and the low frequency mixing products are the output. If you have a 9.75GHz LO mixed with signals coming in at 10.7 GHz, the difference product will be 950MHz. It's incredibly expensive to make a demodulator for Ku-band, and much simpler and cheaper to make one at UHF, so the LNB converts Ku-band signals to mid- to high-UHF for the receiver.

[@NorthcoasterHobby]

@@yakovdavidovich7943 Well-put.👍

[@jedblow]

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 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?

[@NorthcoasterHobby]

I can easily pick up 114.9 W with the Fortec Star dish. I use inexpensive LNBs from eBay. They’re featured in this video: Universal KU Band Satellite LNB’s Explained - Free Satellite Television kzbin.info/www/bejne/a6WzZ6ZnqMiBrcU

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

[@NorthcoasterHobby]

You need to know the diameter and depth of your satellite dish, measured as accurately as possible. The general formula for finding the focal point of a dish is : Diameter squared divided by 16 times the depth. But have a look online, there are lots of sites with this information in much more detail. You very well may not have it aimed on the focal point of the dish. I have also tried pairing an LNB with a different dish and honestly haven’t had much success, but I think if I spent more time on it, I might be able to make it work. It seems to be something that needs a lot of fussing with, getting the focal point and distance just right. I’d say calculating the focal point might be a good general indicator but the LNB will probably need adjusting, and that’s probably best done with a live satellite signal through the receiver or a meter. Thanks for watching.

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.

[@NorthcoasterHobby]

Welcome to the satellite hobby! Here is a tutorial video of the receiver, hope it helps. kzbin.info/www/bejne/fZKsiIVoaph1ipY As far as the dish, it depends on the satellite you wish to receive. That determines the elevation, azimuth and skew angles you set up the dish at. These are all based on your location.What satellite do you want to receive?

[@user-su5sq5ib3i]

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

[@Sam-fb1nq]

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?

[@NorthcoasterHobby]

Could be the size of the dish, a bigger dish is always better in this hobby. A couple of other things to watch are the LNB frequency settings in the receiver and dialing in the skew, elevation and azimuth. A millimeter off can make a big difference. But if you’re getting some channels on each satellite, the size of the dish is probably the issue. Bigger is better with free satellite TV. Thanks for watching!

[@Sam-fb1nq]

@@NorthcoasterHobby - Thanks for the reply. Yeah. Ordered a 99cm replacement. 1 meter is the max in my HOA. It's motorized so i have the scew at 0 degrees. I put the lnb all the back furthest from the dish. Haven't spent a lot of times adjusting since it's on top of my roof and i've been avoiding going up and down since it's about a 30 foot drop off the edge. Have to be very careful with my steps up there! ;)

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

[@NorthcoasterHobby]

Try Dishpointer: www.dishpointer.com/ Enter your location- allowing the website to learn your location seems most accurate Choose a satellite from the list: East satellites are first, then West. Followed by motorized setups and multi-satellite setups for Dish Network, Bell, DirectTV, Shaw, etc. Press ‘Search’ Scroll down a bit. A map with your location appears, along with a box of the dish setup information (elevation, azimuth , and skew) to receive the satellite you have chosen. This information will be the most accurate as it is aligned with your location.

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

The triple does work. I just used it in 2 recent videos, for 97 west kU band and 114.9 west kU band. 950-2150 MHz is standard output range for kU band LNBs.Thanks for watching.📡

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.

[@NorthcoasterHobby]

Did you try adjusting the skew? Rotating the LNB in the bracket.

[@Swenser]

@@NorthcoasterHobby cheers I'll try that.. same issue. I'll crack open lnb next

[@NorthcoasterHobby]

Try adjusting the elevation ever so slightly up and down, that should let in more signal.

Just by feel was a success and found there is a bit of foregiveness in the alignment. I'm getting no sign of any signal capturing on screen when moving all ways. Dead stuck on 45. I'll crack open the lnb .and then order another if can't fix. It was purchased 2nd hand awhile ago not knowing condition. Cheers for helping.
