how to connect 2 receivers to a satellite dish Solved

Question

Hello,
I have a 60 or 65 cm satellite dish with a Canasat subscription, and I would like to connect a TNT Sat decoder for a second TV. I would like to know if I need to change the LNB and the dish; if so, should I use a single LNB with 2 outputs or a twin LNB? I tried using a splitter on my existing setup, but it doesn't work well.

Ccm · Accepted Answer

As already mentioned, make a universal head with 2 independent outputs mounted on a parabola aimed at a satellite of your choice. Two downlines (coaxial cable type 19 Vatc) from the antennas must lead to their respective satellite terminals.
Do not use a splitter or an amplifier.

Ccm · Answer

On the parabola, a universal head with 2 independent outputs is needed.

Hello
Just an idea
If you connect your second TV with a scart cable to a scart output of your TV?
This would force you to watch the same program on both TVs. Anyway, to watch a different program, you would need 2 receivers, right?
Best regards

Hello will a single LNB with two outputs work or do I need a dual LNB? Is my satellite dish big enough? thank you

JCS01 · Answer

Hello
I am not a pro in this field, but it seems to me that 2 LNBs on a dish pointing to the same satellite should work.
If you do not want the same satellite, then two dishes are necessary.
Have you studied the system below (source Wikipedia)

"The DiSEqC protocol serves to control digital satellite equipment ("Digital Satellite Equipment Control") for receiving television via satellite. It allows for example:

- for a satellite receiver (demodulator) to control a motor that positions a dish.
- to switch multiple dishes connected to a receiver via a single downlink cable.
- to receive multiple satellites with a single dish equipped with several LNBs connected to the receiver via a single downlink cable. In this case, the DiSEqC protocol will allow the receiver to select which LNB to use and therefore which satellite to receive. "

Best regards
JC

Ccm · Answer

For Loir 12

Be careful with the confusion: a universal LNB has 1 single satellite input and 1 basic output, but can have up to 8 outputs. A so-called monoblock LNB has 2 satellite inputs separated by 6° but “only” 1, 2, or 4 independent outputs.
By using 2 universal LNBs and an offset bracket, you can receive 2 satellites, but you will need a 2-way Diseqc switch (4-way if using 4 universal LNBs).

JCS01 · Answer

Hello
Thank you for your help Ccm
The need here is to capture a single satellite but to use 2 decoders from what I understand. It would be good, I suppose, if there were only one down cable that could be used by 2 decoders
Best regards
JC

loir12 · Answer

yes, I tried a signal splitter and it doesn't work.

JCS01 · Answer

Yet this seems to be the most normal solution. There must be a bandwidth problem since the satellite signal has a higher frequency than terrestrial antenna signals. The link below shows splitters for satellite.  https://www.gotronic.fr/

loir12 · Answer

Attention, this is not an aerial and the satellite dish I want to connect is two satellite receivers on Astra on a dish. Thank you.

JCS01 · Answer

We may need to install a signal booster (17025: €15)  https://www.gotronic.fr/

Thank you for your responses. I will definitely bring in a professional because I don't want to buy equipment for nothing, and I'll let you know how it went. If you have any other solutions, I'm open to suggestions. Thanks everyone.

JCS01 · Answer

That's great if we can have the solution Best regards See you soon JC

loir12 · Answer

Thank you Ccm for your solution. I put on a head with 2 outputs and it works  thanks

kino · Answer

a double head output simply and especially no splitter, as there is a risk of interference between vertical and horizontal signals

Ludo · Answer

Hello,

How can I connect a terrestrial antenna and a satellite antenna to supply 2 televisions knowing that I use Legrand (Sagane) 3-input sockets for which I can only connect a single coaxial cable between the socket and the splitter?

In short, are there any splitters with two inputs (satellite and terrestrial) and 2 outputs to supply 2 televisions (1 per TV)?

Thank you

Good evening, I'm just arriving on this forum and I have a ton of questions that are clouding my mind, I would like to know: - how to have a Canal Sat signal for life at home? - how to connect an Elta Sat "Sat 170" decoder with an Lnbf head of 10.7-12.75GHz input and output 950-2150MHz and a 95cm satellite dish? - how to obtain a better video signal and what would be the best satellite that broadcasts free channels?   Thank you very much for your response.

Giganté! · Answer

Good evening,
I would like to know how to connect an Elta Sat, Sat 170 analog decoder with a LNB head model n°DUF-2, with an input frequency of 10.7-12.75GHz and an output frequency of 950-2150MHz.
Indeed, I have a 95cm dish with this LNBF from the brand Diplosat, and I haven't been able to get it working since I don't know if the LNB needs power like outdoor antennas or if I should directly connect the cable to the decoder input, which is marked IF INPUT 13.5/18.0V 400mA.
I would also like to know if these decoders require a subscription or if they allow access to free channels with various satellites?
What would be the trick to properly fix the dish to get a good signal, considering I don't have a pointer to do this?

I hope to hear from you, and I wish you a pleasant week ahead.

papy74600 · Answer

If you have 2 TNTsat devices like the Strong 1620, you need 2 separate down leads, so a dual LNB on the dish

If you also have a CanalSat decoder, you will need one more additional cable and a 4-output LNB since there are none available for 3

Check the Surpin site and others for example

Make sure the outputs are waterproof (plumbing self-vulcanizing rubber tape!!!)

An 80 cm dish is preferable if you want to "have the reception" even in bad weather
The bigger it is, the better (especially for HD)

If your devices are labeled HD, be sure to get an HD LNB!!!

Was I clear enough?

papy74600 · Answer

The splitter has no place: You are not on a satellite operating IN ANALOGUE

Each DIGITAL demodulator sends through the cable a given voltage and a polarization data to access a specific station. A splitter disrupts this operation

Immutable rule: AT LEAST ONE CABLE PER DEMODULATOR

The so-called HD heads are actually high-end in terms of cross-modulation

stewartia · Answer

cf the link I provided. But the question is closed, the best thing is to keep it as simple as possible. And it doesn't necessarily have to be very expensive.

Gilles · Answer

again?  the answer is already provided by CCM from message n° 2.  Any other tinkering like 2 decoders on the same line = coaxial = conflicts between 13 and 18 V or between 0 and 22 Khz = random or disrupted reception..  Conclusion, there must be as many outputs at the level of the LNB head and line as there are receivers..

stewartia · Answer

This has nothing to do with the question asked, which is to connect two decoders digitally, not to install a "gaz factory". Basically, a LNB with two outputs, two additional "F" connectors, and a few meters of cable, we check the azimuth, elevation, and polarization angle. This is very well described on the Astra website.

Gerbelin · Answer

Thank you to Gil for his reply.

Moi · Answer

Just attach a twin LNB to the satellite dish and then connect the output to the decoder. Good luck.

Totoche · Answer

All of his answers are very interesting since I am in the same situation:

I have a satellite dish with 1 LNB and 1 output connected to a splitter 1 Input / 6 Outputs
Each Output is connected to a wall socket at different places (6) in the house, but for now we are only using the one in the Living Room. From there, I connect to the antenna input of my Sagem TNTSAT decoder (with Card) which is connected to my TV via a SCART plug. Then I connect from the antenna output of this decoder to the Orange TV decoder, which is connected to the TV via HDMI. The goal of this installation was to be able to record one channel while watching another.
But obviously (given what I have read) it does not work, since you cannot have both decoders on at the same time, otherwise the Orange one disconnects and indicates that the signal is too weak...
If I understood correctly, I need to replace my LNB with one that has 2 independent outputs that will each go to a separate decoder?

Since I only have satellite at home, my splitter will never be useful, so it would be preferable to replace it with a multi-output LNB? Because my children won't be able to watch their own programs in their rooms while my wife watches cooking classes in our room and I watch the F1 Grand Prix in the Living Room lol!!!! Of course, in any case, each one will have a decoder!!!!

crystal54 · Answer

Hello, I'll try to keep it simple. Plus, I haven't read the entire topic, so... here it is, I'm about to set up Orange TV via satellite. I already have a single LNB dish for Canal+, and I wanted to know if it's possible to add a second LNB to receive Orange TV. Thank you for any information if you've already implemented this setup. Have a good evening.

gil · Answer

Good evening,

the technical procedure has already been explained and re-explained in detail several times, depending on the different specific configurations...

a brief reminder of the rule: each satellite receiver is connected to its own output of a single or double LNB head or a monobloc, which has 2, 4, or 8 independent outputs, depending on the satellite dish equipment, whether it is monosat, bisat, or even multisat...

canal+ et orange · Answer

Canal+ is on Astra 19.2 East - like TNTsat - Round dish of 60 to 80 cm
Orange is on Atlantic Bird 5.0 West - like FranSat and the Bis bouquet

The gap of 24.2 degrees implies a second round dish of 80 to 100 cm

You can also use a single elongated dish like Visiosat TriSat
In this latter case, you can also add an LNB for HotBird 13.0

ALWAYS A DROP FOR EACH DEMODULATOR

If you are also using TNTsat or FranSat, you can remove the usual antenna and use the drop cable for an LNB !!!!

papy74600 · Answer

The UNIQUE ROUNDED parabolic technique has already shown its limitations It doesn't work every time On the other hand, there's no issue with an OBLONG TRISAT (with the added pointing software provided)

virginyie · Answer

To have a second decoder, I need to change the antenna head of the satellite dish. Do you have any idea what that might cost?

maxence · Answer

Hello With Fransat, you can connect multiple decoders to the same satellite dish with just one LNB and, importantly, one single cable, allowing you to watch different programs on each TV. This is impossible with TNT SAT, which broadcasts on both polarities. I have installed 4 FRANSAT decoders in place of 4 analog ones on an 80 cm dish that has been installed for a few years, and everything works. Best regards

Arsène Lupin · Answer

I understood everything well, 2 decoders = 2 heads, etc. but in my case, I can only have one down cable. I have a Philips DSR 7121 decoder with 2 tuners and two inputs. If I receive the same channel on both tuners (one to the TV, the other to the hard drive), will there be conflicts in the case of a splitter? Thank you for your answers.

gil · Answer

x th Reminder :  With a splitter (Bis Commuted), conflicts only arise when the channels selected on the decoders do not share a common frequency band and the same polarization  If it is the same channel, the question does not even arise since it necessarily has the same parameters!!  If it's a channel from the 3 bouquets, Fransat, Bis TV and TV Orange on Atlantic Bird 3, it is in the same band and polarization. (Bis Simplified)

OK Thanks, that answers my question.

Ronceveau · Answer

Pour alimenter deux récepteurs TNT avec un LNB à une seule sortie, vous pouvez utiliser un répartiteur. Connectez la sortie du LNB au répartiteur, puis reliez chaque sortie du répartiteur à un récepteur TNT. Assurez-vous que le LNB est compatible avec la réception de deux récepteurs simultanément.

stewartia · Answer

You need a twin LNB: https://www.2galli.fr/ and "pull" a second cable: https://www.2galli.fr/ 2 additional F connectors: https://www.2galli.fr/ see two sealing sleeves: https://www.2galli.fr/accessoires,fr,2,71.cfm  Finally, you do not need to change the dish, if necessary, check its alignment as described here: https://fr.astra.ses

janneau · Answer

Hi, you need to know that to supply two, three, or four TVs you should use  a universal LNB, for example (quad LNB head UST 2-3-4) with independent outputs  so a cable that goes from the LNB to your TV. I have 4 TVs, they all work  together without distortion  if you want an example, take a watering hose to which you connect two other  hoses, and you will lose flow. However, if you connect several hoses to your  main supply, you will have the same pressure on all your hoses.

drissart · Answer

Hello, yes we need to buy a new head and a new dish because they aren't aligned in the same direction.

suds · Answer

Hi, I'm adding a question:  Same thing, a satellite dish but 2 decoders (1 for Canal and 1 for Strong):  Lazy person's solution: can we simply change the cable from decoder no. 1 to no. 2 and vice versa as needed (for example: we are watching Canal, I want to switch to TNT, I unplug the cable from the Canal decoder and put it on the TNT satellite decoder)?  Is that possible? (besides the inconvenience of access)  Thanks

pcaudio · Answer

Keep the LNB and the dish oriented at Atlantic Bird 3 at 5 degrees West (diameter may be a bit small)  you will have Fransat (card valid for life and much better sound and more free channels than TNTsat locked CanalSat)  but above all FranSat works in simplified BIS so a splitter is enough and you can keep the already wired installation  get Fransat terminals like the Wisi in SD or the mixed HD Aston FranSat HD terminal  I have both because the Aston demodulates 3 satellites on a single Disecq cable

castor · Answer

It seems you haven't read what has already been said on this thread or haven't understood the explanations.....  It's simpler, just take a look at this satellite antenna installation diagram for 2 outlets  http://images.imagehotel.net/krgpu3frgt.jpg  (be careful of bad advice, like splitters and "T")

Hervé · Answer

With the canalsat decoder, it's not complicated; on this decoder, there is a satellite input for the decoder, and then a satellite output for the next decoder. That's it, problem solved. My problem is that I don't have this output on my decoder, so I don't know how to connect my two decoders. If you have a solution, please let me know...

kristo · Answer

you put a simple head with 2 outputs, but you need to run an additional cable either for TNT or for Canalsat to separate the two satellite sources.

castor · Answer

2 terminals or 2 decoders or 2 demodulators, or 2 televisions, or 2 receivers, whatever the name*, but all with a tuner compliant with the DVB-S or DVB-S2 standard, the connection and installation are extremely simple see the satellite dish installation diagram that highlights a universal LNB head with 2 outputs:   Astra: (Tntsat) http://img266.imageshack.us/img266/3991/teteuniversellelnb2sort.jpg  Atlantic Bird 3 (Fransat) http://img716.imageshack.us/img716/8145/tetelnbuniverselle2sort.jpg  *Demodulator being the historical term, professional jargon, with terminal.

stewartia · Answer

It's quite simple, you need to replace the LNB "single" with a "twin", meaning two distinct outputs: https://www.2galli.fr/ you need two cables, one for each output and for each receiver. You need to remove your Télévés box.  On the site I just mentioned to find an LNB, you will find cable by the meter: https://www.2galli.fr/ "F" connectors: https://www.2galli.fr/ waterproof sleeves if you want: https://www.2galli.fr/accessoires,fr,2,71.cfm and for AB3 you could take a larger dish: https://www.2galli.fr/parabole-aluminium-al78w-80-x-73-cm-label-ws,fr,4,AL78W.cfm it's an inexpensive and very effective aluminum model.
