Help Required 4 LNBs 4 TVs... HELP!

[HutchRN]

Well my title more or less says it all, I am at a complete loss!

I have 4 LNBs on a Triax Multibracket, all the individual LNBs receiving signal from 4 different sats quite happily.

Connected my 28.2E Sky UK LNB to my 4x8 Switch today, and only either V or H comes through depending on what I connect it to.

Now it is my understanding that I may have got things slightly wrong and my 4x8 Switch may only actually be able to deal with 2 LNBs (ie i need dual LNBs into the two paired ports), in which case I would really appreciate some advice on what I need to do to get my 4 LNBs to feed into my 4 RXers (is there such a thing as an 8x4 switch?).

As you can see I am quite confused :-)

 

[timo_w2s]

It sounds like this 8x4 switch could be for a quattro (not quad) LNB to allow 8 outputs from a Sky dish (the same thing as an octo LNB will do). Can you post more details on this switch please and also what satellite receivers you are trying to connect it to and the type of LNBs you have.

If you want all 4 LNBs on the Triax dish to feed all four receviers you'll need at least four DiSEqC switches for each receiver. If the receivers need two LNB inputs (eg for recording facitlities) you'll need two DiSEqC switches for those receivers and the correct number of outputs on the LNBs.

Standard Sky boxes do no work with DiSEqC switches so these would be better connected direct to an LNB pointing to 28E.

This is the switch I have

I was kinda hoping to at least run 2 LNBs through it, if I were to use a pair through the 0k and a pair through the 22k would that give me what I need?

At the moment I have single output Triax LNBs however I have Dual Output LNBs on the way (if i need quads I can still take care of this)

That switch requires a quattro LNB from a single satellite, the quattro LNB gives four different outputs which match the inputs marked on the switch. As far as I am aware, Dual LNBs (as were used in multiswitches) are no longer made, they used to have two separate/different outputs, one horizontal and one vertical, a twin LNB has two identical full universal outputs. Now if you were watching packages from different satellites which were exclusivel on high band on one and low band on another, then you could probably make it work, but it would still be fiddly.

If you want to watch the full content on four different satellites in 8 different rooms, you need a 13/8 multiswitch and in most cases, four x quattro LNBs.

So many satellites (4) and only 4 outputs, is not very normal, if 8 outputs.
Tantos satelites (4) y solo 4 salidas, no es muy normal, de 8 salidas si.


Own a multiswitched 1 satellite (4 polarities) for 8 tuners.
Care Rolfw, 13 entries are three satellites in full (4 polarities each satrelite) + Terr Input.
As you only want 4 full satellites, to feed 4 tuners, seeks a multiswitched unit 16 or 17 inputs (4satelite + Terr Input ) which can be cheaper and 8 outputs.
--------
Tienes una multi conmutada de 1 satelite (4 polaridades) para 8 sintonizadores.
Cuidado Rolfw, 13 entradas son 3 satelites al completo (4 polaridades cada satrelite) + entrada Terreste.
Como solo quieres 4 satelites completos, para alimentar a 4 sintonizadores, busca una centralita multi conmutada de 16 o 17 entradas (4satelite+entrada Terreste) que puede ser mas barata y 8 salidas.


As you have to change the LNB's 1 out you have now for these other (4 polarities/band), this announcement, it's any reference to find what you need.
Como tienes que cambiar los LNB's 1 salida que tienes ahora por estos otros (4 polaridades/banda), este anuncio, te sirve de referencia para buscar lo que necesitas.

Something more expensive.

The somewhat cheaper option B is to universal LNB 4 outputs and 4 DiSEqC throwing a line to each tuner.
La opcion B algo mas barata es poner LNB de 4 salidas universales y 4 DiSEqC tirando una linea hasta cada sintonizador.

 

[HutchRN]

Just to let people know where I went with this...

The switched took the 4 inputs from a quattro LNB, and split it to 8 outputs

I have purchased 3 more of these switches and put all 4 of the 4x8 switches into individual LNBs

I have then taken an output from each 4x8 switch and fed it into a 1x4 switch, this has worked fine.

I now have 4 tvs working on 4 LNBs from one dish :-) happy me!

Thanks for all your help guys!

 

[HutchRN]

And for those of you who weren't confused enough, here is a really rough diagram :-)

 

[Tururu]

That's the option C, is the most expensive and complicated by the necessary wiring.
The good thing is that if in the future you want to put up to 4 tuners more, everything is ready and you just need to buy a DiSEqC for each tuner and put the cables.

It is also a signal that more losses added to the installation, if you are happy, perfect.
PS: Do not forget to also congratulate the seller's shop.
-----------------------------------------------------------

Eso es la opcion C, es la mas cara y complicada por el cableado necesario.
Lo bueno es que si en un futuro quieres poner hasta 4 sintonizadores mas, esta todo preparado y solo necesitas comprar un DiSEqC para cada sintonizador y poner los cables.

Tambien es la que mas perdidas de señal añade a la instalacion, si estas contento, perfecto.
PD: No olvides felicitar tambien al vendedor de la tienda.

 

[HutchRN]

What shop tururu? I did that all with stuff I had lying about at work!

I see what you mean about wiring, however with the signal levels I am getting from a 1.1m dish located where I am, the losses are not significant here.

As for wiring... can't say it was that difficult :-)

[HutchRN]

As I have come to understand it, this is fine if you are using QUAD LNBs, I am using QUATTRO LNBs

Yes, Quads basically have the 4x multiswitch built into them. Quatros are useful for larger installations where more than 4 outputs are needed. With your setup you can add extra outputs fairly easily for a PVR or extra TVs.

 

[Terryl]

This switch would be a better choice, less things to go wrong.

[Tururu]

I fully understand the difference LNB QUAD =/= QUATTRO LNB
QUAD LNB Universal LNB = 4 in a box.
QUATTRO LNB = 4 outputs (band/polarity).
Low band/horizontal polarization, high band/vertical polarization, low/vertical and high/horizontal.

We discuss the multiswitch you have supports put LNB's quad or QUATTRO according picture and almost all Multiswitch are similar, not necessary to put this team if you only want to connect 4 tuners as comment only with the 4 switches/DiSEqC is enough.
---------
Lo comente, el multiconmutador que tienes soporta poner LNB's quad o QUATTRO segun foto y casi todas las centrales multiconmutadas son similares, no siendo necesario poner este equipo si solo quieres conectar 4 sintonizadores, como comente solo con los 4 conmutadores/DiSEqC es suficiente.

As the initial equipment is 8 tuners, indicating reference Ebay with 8 outputs + 4 LNB.
With only 4, as the partner is cheaper without LNB's headed GBP 109.22.
---------
Como el equipo inicial es para 8 sintonizadores, indique referencia de Ebay con 8 salidas + 4 LNB.
Con solo 4, como indica el compañero es mas barato, sin los LNB's sale por GBP 109,22.

I think the same, fewer cables, fewer breakdowns.
You asked how to do the installation.
Not see you lost signal by having much signal does not mean you will not have lost my job is to see that information/data.
As comment, if you are happy, perfect.
--------
Opino igual, menos cables, menos averias.
Preguntaste como hacer la instalacion.
Que no veas perdidas de señal por tener mucha señal, no quiere decir que no tengas perdidas, mi trabajo es ver esa informacion/datos.
Como ya comente, si estas contento, perfecto.
