Help Required How to watch signals simultaneously from multiple LNBs with a single cable to the receiver

[hsbrar]

Hi All,

We have 2 dishes.

Dish 1 has a Monoblock LNB plus a single LNB.

Dish2 has 2 seperate LNBs.

Each dish has one 4x1 Diseqc switch to which LNB cables are attached,so there are two Diseqc switches for 2 seperate dishes.

The two cables coming from 2 seperate dishes via Diseqc switch are further connected to a 4x1 Diseqc switch near the Set Top Box.

Now how to watch all LNBs together with a single cable in the set top box ?

What the Diseqc settings on the receiver for watching all channels together without the need switch the cables on the Diseqc switch.

Can any techie help ?

Thanks

Throw away Monoblock and replace it by 2 Single LNBs. Also throw away 4/1 Diseqc switch and replace it by 1/8 Diseqc switch. That is all you should do.
In addition, you could post couple of pictures of your installation.

Depends on the type and models of the LNB's.

You could go with an 8x1 multi switch, this would give you all LNB's into one switch, however the types of LNB's used complicate things a bit, also the satellite receiver needs to be able to use Diseqc 2.0 switching.

The best problem free setup is to use all the same type and brand of LNB's, this avoids switching and compatibility problems.

Some LNB's use a DC voltage to switch between satellite transponders, others use a 22 KHz tone, the two types sometimes don't mix too good, (I said sometimes) so using all the same types of LNB's helps with the setups.

If this setup is only going to be used with a single receiver then you should have no problems using an 8x1 switch. (take a look at EMP-centauri switches)

The first thing you need to realise is that there is another Disecq switch inside the Monobloc, so things are going to get very interesting indeed trying to get that lot working!

As the other lads have said you are probably best getting an 8*1 switch and just rewiring everything into that.

Thanks all for your suggestions but it seems I forgot to mention that the 2 dishes are placed very far away ie one in the balcony and another on the roof so 8x1 Diseqc switch can not work for both the dishes together.
Only possibility is to place the 8x1 Diseqc near the receiver to get signals from both dishes.

Then you probably need to have 2 cables to the receiver. When you have 2 cables (one from balcony and another one from the roof), then nave 1/8 Diseqc switch near receiver and 2x 1/4 switches near antennas. Anyway, the monoblock must go. It is also possible (and, BTW, very advisable) to change your receiver to Twin tuner receiver.

Thanks for the suggestion.
Actually Twin tuner receivers are not available here and I dont feel like getting one from China or elsewhere as the thug customs dacoits here charged me 17 dollars custom duty for an item worth 29 dollars from China last time.
We use Monoblock LNBs here to get 2 satellites at a time .It is usually used here to get NSS6@95e and Asiasat5@100e with equally powerful signals.
It can be used for other satellites also.
Yes I have 2 cables coming from 2 dishes which at the moment have one Monoblock LNB each and now I have changed to a 1/8 Diseqc switch near the receiver.So far setting is simple but things will get completed when I add more LNBs(Even if I get rid of Monoblock LNBs) and put Diseqc switches near both dishes.
That is why I am requesting for the Diseqc 1/8 settings on the receiver.

If you already have 1/8 Diseqc switch near the receiver and 2 cables to your antennas then oy only need to trow away monoblocks and install single LNBs instead of them. Then put 1/4 Diseqc switches near each antenna and configure your reeceiver (whatever brand it is) to work in cascade mode.

My receiver is AZ Play which is also known as Openbox Mini and it has Diseqc 1.0 and Diseqc 1.1 settings.
By the way what do settings A1,A2 etc and B1,B2 etc mean in Diseqc 1.1 settings ?

 

[Analoguesat]

There will probably be tiny dip switches on the body of the 8*1 switch to allow different configuration use. Change the dips to Disecq 1.1, connect all the cables up to the switch and set your receiver up.

So, to understand your questions better:

- How is your monoblock connected to your first 4/1 switch?

- Of what diseqc protocol are your (4/1) diseqc switches, diseqc x.0 or x.1? Is the 4/1 switch near the settopbox of the same protocol?

- How do you mean this:

....without the need switch the cables on the Diseqc switch.

Which cables do you switch?

- Are the LNB's you use in your country 'universal' LNBs, with two LOFs (high band and low band, using 22kHz signal to switch between them)? Or 'standard' LNB's with only one LOF?

- Does your receiver support diseqc 1.1 or 2.1? Edit: Ah! You already answered that question!

NB If your receiver has diseqc repeat and/or can manage diseqc command order, and when you want to add more LNB's than you have now, you have the possibility to do the following:

At your receiver, use one of your 4/1 diseqc 1.0 switches, and connect it to the two cables to your two dishes.

At your two dishes, you can then use a diseqc 1.1 switch. You can use any diseqc 1.1 switch you like, from 2/1 to even 16/1!

When you really need the monoblock, you could also use that in this configuration. (For that to function properly, you really need the diseqc repeat!)
In that case you'd have to change the 4/1 diseqc 1./0 switch by a diseqc 1.0 2/1 OPTION switch.
Or (still using the 4/1 switch) you'd have to split the cable-from-the-dish-with-the-monoblock-LNB to inputs A and B of the 4/1 switch (using the C-port for the other dish/cable), or modify the 4/1 switch internally, to reach the same effect.


When you have only single-LOF LNBs, you could also make a setup with a 22kHz switch.
Also there are 0/12V switches, and manual switches, to prevent you from switches cables.

BTW: What exactly are the diseqc 1.1 settings possibilities in your receiver? A1/2, B1/2, C1/2 and D1/2?
ABCD would then mean the UC-level (UC=uncommitted command), I guess. In the receivers I know, the numbers 1 till 16 are used....

I may be wrong but so far I have noticed that 1,2,3 etc represent the satellite numbers whereas A,B,C,D represent the LNB port numbers in my Diseqc 1.1 ie 8/1 Diseqc switch near receiver and 4/1 Diseqc switch near Dish.

So far as Monoblock LNB is concerned I would like to inform that I am getting the very weak TP 12721 of Telstar18@138e which is not even meant for our region ,on my 2 feet dish whereas this is not possible with a single LNB.

Actually here Monoblock LNBs are used by a DTH company called DishTV so they are of high quality.I have been able to get a number of nearby satellite combinations with Monoblock LNB although here this Monoblock LNB is used to get NSS6@95e,Gsat@93.5e and Asiasat5@100.5e simultaneously.

I wish triple Monoblock LNB were also available here as we can get 3 or 4 satelites simultaneously.

Keeping in mind the above I would not like to throw away my Monoblock LNBs as suggested by some member earlier.

They will probably be cheap Chinese equipment sourced by DishTV to a budget. Some will be good, some will be bad. Looks like you have a good un.

Televes and other manufacturers have DiSEqC 4x1 that support a Monoblock.
The operation is simple, if you put a monoblock, you change a position switch and the monoblock works correctly.

Televes y otros fabricantes tienes DiSEqC 4x1 que soportan un Monoblock.
El funcionamiento es sencillo, si pones un monoblock, cambias un conmutador de posicion y el monoblock funciona correctamente.

Televes ref,. 7269 ...In the forum for years commented.
Option A OK, option B and C have many losses.

@hsbrar
For monoblock of 3 satellites, option B would be the most indicated, commercially there is nothing (remember).
Para monoblock de 3 satelites, la opcion B seria la mas indicada, comercialmente no hay nada (que recuerde).
