Splitting a Satellite TV Signal to Multiple Receivers - Free Satellite TV

- Simply using a splitter to split an FTA satellite signal isn’t such a simple option. The main reason is that free satellite TV channels are linear polarized, meaning that signal wavelengths are oriented in either vertical (V) or horizontal (H) linear wavelengths. This means your receiver and LNB have to switch between the two polarities because only one type of polarity can be sent down to the receiver at a time. This means using a splitter to split a signal off a single LNB to 2 receivers will result in one receiver becoming the control receiver taking care of the polarity switching, while the other receiver becomes a follower receiver, capable of only receiving channels that are on the same polarity as the control receiver (H or V). Using a splitter might be a viable option for you if you can live with only receiving one polarity of channels or the other on a second receiver. Other options that will give each receiver full independent control of all channels include using a multi-output LNB, or a multi-switch, which must be used in conjunction with a dual-output LNB.

More specifically, cable TV splitters normally pass rf signals but no DC current. Some splitters have DC diode steered outputs. Look up Holland HFS - 2D. DirecTV uses DC power pass splitters MSPLIT2R1 - 03. Holland makes a splitter with DC current from input to one output DPD2. Another oddity is a tapped splitter. In to out is strong, but a third connection tap is attenuated 12 DB. See DC Communications GDC - 12ND . ...It is the DPD2 that will immediately isolate one receiver from powering the LNB and keep the two receiver power circuits disconnected from each other.
Thanks for the information.
You sole my idea for your upcoming video, good thing it was free...🤭
You inspired me. 📡📡📡😄 my first video on this topic left a lot to be desired.
🤣
Splitters are no good. You can also connect multi-dish with DiseqC multiswich into one cable to your receiver. This is supported by all receivers today (or should be). The reason why you can only watch one channel (or transponder) in this setup has nothing to do with polarization of the signal. This has everything to do with the LNB. Since it only provides one signal at the down converted frequency to the receivers. For multi-receiver setup your only option is using a multi-output LNB. Other option, that I don't know if works for Canada or U.S is to get multi-head LNB (many have multi-output, two and up to eight). That way you can get a signal from two satellites at once. There are several versions of this out there, some use DiseqC and some don't.
Over the air signals are polarized, its either vertical or horizonal polarization that is being used at the transmitter. Same goes for cable, but its less of a problem in a cable system than in over the air system.
DiSEqC works for connecting multiple LNB’s to one receiver. The fact that only one polarity is delivered at a time by the LNB limits the capability of a splitter. A multi-output LNB is best for independent control over all channels at each receiver. Cable and OTA signals may be polarized but it’s a non-issue if they’re all on the same polarity.
In Canada we have Shaw Satellite dishes with dual universal LNB units, with built in multi-switch. Capable of receiving 2 satellites offset by 4 degrees on the arc. They have outputs to connect up to 4 receivers.📡
I agree you are getting to know a lot about this stuff. Thks for spreading the knowledge
around. I read in someone's comments, they mentioned DiseqC I never new what that was. I
know I leave it disabled. From reading what you said to someone else, it's if you have more that
1 lnbf . I guess that's only for those small ku dishes , Do you have any lnb's doubled up? I have a 7&1/2 ft c band mesh so I wouldn't ever use the DiseqC , Don't know how to say it . it's like a
couple off abb. put together ( DiseqC )
I do use DiSEqC switches. I have C and KU band LNB’s combined on them. Here’s a playlist of videos I’ve made on satellite switches:

Thanks again for watching, I appreciate the comments.📡
Good video. Quick question for you or anyone else who may be able to help. I have 2 satellite dishes pointing at different satellites each of them with a duo LNB. In my TV room I have 2 receivers, each of them locked to a specific satellite (they are not diseq capable). It is very hard for me to run 3 additional cables to my living room, so my questions are:
Can I combine the 4 signals coming from the 2 dishes (2 from each duo LNB), drive this signal through the one existing cable to the living room and then split it into 4 signals to feed each of my receivers (2 LNB ports each)?
If so:
- What would be the right way to do this?
- Could I watch channel 1 on Sat1 and record channel 2 on the same satellite at the same time on the same receiver (this works if I run the 2 cables rather than one )
- Could I watch channel 1 on Sat1/receiver1 and record channel 10 on sat2/receiver2
The above obviously works with no issues when I run 4 individual cables but I am wondering can I run all this through the one single cable and what the best way to achieve this would be.
I guess I don't need the diseq switch since I have each receiver pointing at each LNB port on the satellite dishes, but wonder would combining the signals and then splitting them cause any issue. Would this work?
Is this what the use for the multiswitch you talk about at the end of your video and would that work for more than one LNB/Sat or would it only work for a single LNB with multiple ports?
thank you
n Europe there are some satellite pay TV operators that broadcast all their channels on one band. For example one operator will choose for example the Vertical Low Band. On the Vertical Low Band the satellite pay TV operator will broadcast all their channels. Making the reception like cable TV. All you need is a single Universal LNB and a 2 - 4 satellite splitter. To connect more than 4 satellite receiver and i'm referring to hotels or motels a multiswitch is the best solution. But most satellite operators will use all bands. In my case I use splitters because all my TVs have satellite tuner and I also use a satellite receiver. The reason that I use the satellite receiver is that the TV doesn't have USALS function only the receiver. When you use the TV it is mandatory to power off the satellite receiver, and when you use the satellite receiver it is mandatory to disconnect the TV from the LNB.
Absolutely. Power off and disconnected for sure. It would be much easier to have all channels on one polarity like cable. But it’s the nature of the hobby I guess.
@@NorthcoasterHobby Let me tell you something that will make everyone confused about LNBs and it's mostly in Europe There are some LNBs in Europe that use two polarities instead of one either vertical or horizontal but they use the frequency band from 300 MHz up to 2400 MHz Those LNBs have two outputs one for Full Vertical Band and the second for the Full Horizontal Band. These are called Wideband LNBs. I But you still need a special multiswitch. Cascadable dSCR Multiswitch. One that has two inputs and four outputs. Two inputs for Wideband LNB and four outputs but those four ouputs are VL, VH, HL, HH not outputs like a Universal LNBs but these are cascade multiswitches. In order to connect a Cascadable dSCR Multiswitch to a satellite receiver you need a clasic multiswitch. The classic multiswitch has 4 or 8 inputs in this case we need the one with the 4 inputs and has from 4 up to 32 inputs that connect directly to your satellite receiver. This type of switches and LNBs are used in hotels. If you connect a Wideband LNB to your receiver will be problematic. Also there are fiberoptic LNB. That type of LNB is powered by a coaxial cable with 20 Volts (the voltage must be permanently) and has one fiber optic output. Again you need a converter from fiber optic to cable.
@@Nicholas_Chris Wow, sounds complicated.
I dont know if someone can help me with this but i installed a splitter that has power pass on a single port. The main receiver ( connected on the power pass port) work like its supposed to but the other one on the other port is very slow when i turn it on it takes like a full 1min to show something on the tv
I know your talking about splitter , but are their distribution amps for satellite similar to the ones use for ota?
They do have those, actually.📡
Would love to know if It's worthwhile doing this setup living in eastern Canada. Looking for US stations and Euro soccer. Any idea what the best dish size would be?
The bigger the dish the better. I’d get at least a 39” dish. NBC and COZI TV are on 103 West KU Band. PBS and its sub channels are available on 87 West and 125 West KU Band. C band has more US channels available. You may get some soccer on Galaxy 19 97 West KU Band.

I was wondering how come i lose signal when i switch on my second reciever
It could be because the second receiver is tuned to a channel on the opposite polarity as the primary receiver.
Nice
Thanks for watching!
