Missing diseqc switch?

[Richard1963]

I needed a duo LNB with twin output

canaldigitaal | DUO LNB

However my installer instead installed two single LNBs one for 19.2 and one for 23.5.

My receiver (an M7 MP201) has two inputs so in theory I should be able to record but all I can do is watch programmes sent on one of the two satellites (depending which way I connect the cables to the two inputs) and recording doesn't work

I'm guessing I need to introduce an external diseqc switch? If so, can anyone confirm exactly what sort I need in order to receive programmes from both satellites at the same time and for record functionality, and is it possible to provide a link?

No, you need to replace one of your existing single LNBs with a dual LNB, and keep this on the inputs of the STB.
If you *do* want to have two sat positions, you need 2 x dual LNBs, AND dual DiSEqC swtiches.
The receiver/STB often gets really confused if you hook different sats to two inputs.

You probably also need more cabling. If you have a dual input STB, you need a cable per input...

Como tal es un monoblock para 19.2 y 23.5.
Una caja con 2 LNB's y un conmutador (2x1).

Ya tiene el DiSeqC dentro y el receptor selecciona que satelite quieres.
Creo entender que tienes el sencillo, solo una salida, lo tendias que cambiar por el doble/twin que tiene 2 salidas.
El twin es como tener 2 en una sola caja.
Bajas los 2 cables al receptor, uno a la entrada 1 y el otro a la entrada 2.
El receptor configurado para usar el DiSeqC, tienes que configurar los 2 tuner/entradas, cada una por su lado.
De esta manera tendrias en los 2 tuner los 2 satelites al 100% para realizar grabaciones.
Tendrias que saber que satelite tienes en cada posicion/boca A/1 y B/2, para asi configurar el sintonizador correctamente.

As such it is a monoblock for 19.2 and 23.5.
A box with two LNB's and a switch (2x1).
DiSeqC already has the inside and the satellite receiver selects that you want.
I think you understand that simple, only one output, you tended to change for double / twin has 2 outputs.
The twin is like having 2 in a single box.
Low 2 wires to the receiver, one to the input 1 and the other to input 2.
The receiver is configured to use the DiSeqC, you have to set 2 tuner / entries, each on its side.
In this way you would have 2 satellite tuner 2 to 100% for recording.
You would have to know that satellite have in each position / mouth A / 1 and B / 2, so the tuner set correctly.

Como esta diseñado para antena Triax 64cm, si la antena es mas grande no funcionara bien pues la separacion de 4º+/- no coincidira.
Si no es una Triax64, necesitas una antena de 70x65cm +/-.
----------
As is designed to Triax 64cm antenna, if the antenna is bigger not work well because the separation of +/- 4th will not match.
If it is not a Triax64, you need an antenna +/- 70x65cm.

So, why didn't your installer install the CanalDigitaal twin duoLNB?
Is it because he thought the LNB didn't fit the size of your dish (what size is it?) for 19E +23E in London?
Or is it because he thought he would find his own 'solution' to what you wanted? Then it might be a default?!

With a twin receiver you are right to want twin LNBs or a twin monoblock LNB.
The single LNBs give much less functionality.

Edit: Ah, I see your dish is a 80cm dish; that could really be problematic for this 'duo-LNB'!
I believe 4degree monoblocks for 80cm dishes do exist, but I'm no expert at that.
Two twin LNBs and two 2/1 diseqc switches to the two cables would do the job perfectly on this 80cm dish.
If you really want the duo-LNB, you have to switch to a 60cm dish....

Los monoblock de 4º para antena de 80cm si exiten/The monoblock 4th 80cm antenna if exiten: Monoblock 23mm LNB ,4° for 80cm dish/

Este es sencillo/This is simple: Inverto - IDLB-SINM24-DOPO4-8PP -
Doble/double:Inverto - IDLB-TWNM22-MNO43-8PP -

Por eso el aviso del tamaño de plato que necesita para el monock que tiene ( DUO LNB.), esta diseñado para una Triax64 (70x65cm).
Ahora tiene 80cm (85x80cm) segun sus datos, con esta antena dara menos rendimiento al perder parte de la señal.
-----------
So notice dish size you need for monock having (DUO LNB.), is designed for a Triax64 (70x65cm).
Now has 80cm (85x80cm) according to their data, this antenna will give less performance to lose some of the signal.

Thanks for your help. I had assumed the duo was simply 2 singles with an internal diseqc switch but I see there is more to it because of the twin output. I have decided to go with the inverto monoblock.

BTW
Triax td 64 has 60cm width and 65 cm hight, according to triax specs ( https://www.satsol.co.uk/ProductInfo/C51858/C51858.pdf or Triax - TD64 std. RAL 7035, singlepack - Flange nut )
Just to be precise...

Look to review the characteristics of the antenna before putting the information and then dance data, please advise, and I found the guilty finger
Spain is well known in the TD54 model, the company installed digital VIA for its customers oriented Hispasat at 30°West.

Mira que repase las caracteristicas de la antena antes de poner la informacion y luego bailo los datos, gracias por avisar, ya encontre el dedo culpable
En España es muy conocido el modelo TD54, la empresa VIA digital la instalo para sus clientes orientada al Hispasat a 30ºOeste.

PSo antennas referenced as the rest/No referencian las antenas como el resto.;)

No problem, no need for "a guilty finger" (funny expression, if I understand it correctly, as native dutch person).

That way we all share our knowledge... .

El dedo culpable es el mio, al no estar bien colocado sobre el teclado.
Es un problema fisico, suelo tener cuidado.
Disculpa por la expresion, no es un dedo acusador que señale.

The culprit finger is mine, not being well placed above the keyboard.
It is a physical problem, I usually take care.
Sorry for the expression, it is not to point an accusing finger.

De schuldige vinger is van mij, niet goed wordt boven het toetsenbord geplaatst.
Het is een fysiek probleem, heb ik de neiging om voorzichtig te zijn.
