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.

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.

  Good evening,
  I have the same problem as the first person, which is: 1 dish, a Canal Sat decoder and an Orange TV decoder
  I bought a splitter: 1 satellite input, 2 outputs: 1 to Canal Sat and the other to Orange TV (I thought that was enough !!!!!)
  Well, NO!!!!
  Orange support told me that I needed a dual LNB (with 1 output or 2 outputs?)
  And a friend told me that I needed a single LNB, but with two outputs
  Can you advise me?
  Thank you

  It has been dozens and dozens of times that we have answered the same question regarding the universal head with 2, 4, or even 8 outputs in a collective antenna ... for 2, 3, or 4 and up to 8 satellite terminals

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

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.

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

  Hello,
  I installed a dish with a dual output, one going to the SAGEM HD decoder and the other to the STRON decoder, but only one powers the dish. It works very poorly; the connection of one TV blocks the other TV on certain channels. IN SHORT, I DON'T KNOW WHAT ELSE TO DO.

  Nothing could be easier without buying anything. You take your cable coming from the satellite dish, strip it 5 to 10 cm from the end, being careful not to cut the shielding (the braid). Separate the braid and strip the core so that it is visible. Do the same on the end of another cable that you will have previously cut (the length you need to connect to the other decoder). Connect the braid of this cable to the other braid and the core to the other core, ensuring that there is no contact between the grounds and the core. Connect each cable to its decoder and everything works without any investment. Tape it all together (I have connected both the Canal+ decoder and the Orange decoder to the same satellite dish).

  Thank you, Pompon, for the explanation. Can't we simply put a tee at the end and connect each branch of the tee to a decoder?

  You simply need to install a "twin" LNB, it's an easy installation, and unlike tape, it will hold up over time.

  The relevant and compliant solution was given from the first response; however, it is not necessary to implement all the advice, as some are inappropriate, stemming from the so-called capacitive coupling, known to RF technicians and amateur radio operators...
  
  Furthermore, on the forum, regarding the "T," how many times have we read that "T's" are prohibited due to the lack of necessary impedance compliance, yet we are heavily witnessing their usage being mentioned...

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...

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

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!!!!

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

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).

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?

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

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

  LNB HDs do not exist, it's just marketing.
  Get an MTI at 7.90 euros in 0.2dB, it will do everything but the coffee.

To be able to watch different shows on each television, we can also adopt tri-tuners, like those made by Neli:

Giganté!

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.

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?

  Thank you for the information.
  But I bought a dual-output LNB, one for Canalsat and one for 2 Strong TNT decoders with a splitter. The images are stuttering, so what can I do? Would an amplifier solve this problem? When only one TV is on, it works well; I get good reception, but when I turn on both decoders at the same time, the image stutters and I cannot receive certain channels because the signal is too weak.
  Best regards.

  a HD LNB doesn't exist.......... the difference is made at the level of the HD or SD demodulator.. I don't know of a Strong 1620 for Tntsat, for the LNB you need a monoblock with 2 or 4 outputs depending on......

Answer 19 / 57
canal+ et orange

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 !!!!
