LNB - Mono/Dual feed & motorizzato
Salve,
stavo valutando di passare da un mono feed montato da Sky per il MySky HD, con LNB con due calate unicable SCR, ad un dual feed.
Oltre a Hotbird 13E pensavo di puntare pure Eutelsat 9E perché a quanto ho visto ci sono un sacco di canali nazionali di TV locali e non, la maggioranza FTA. Astra 19E sarebbe l'altra alternativa mi pare invece più "Europeo".
Trovare un LNB da 4° con due uscite è già abbastanza complesso, con un paio di uscite SCR pare impossibile.
Che voi sappiate va bene qualsiasi LNB per MySky HD oppure è indispensabile proprio Unicable SCR?
Se trovassi un dual-feed con una sola uscita potrei "sdoppiarla" con uno splitter oppure ci sono controindicazioni?
Grazie.

Re: LNB - Mono/Dual feed & motorizzato
Can you confirm that you can set up a dish, and see the satellites of 9e/13e /19e.
If so you could use a 80cm dish with a 4 way diseq switch with normal single lnb's, or even better use a motor with the 80cm dish.
Have a look at (dishpointer), put the (X) to were you would put your dish, then you will then be able to see if you can receive those satellites.

Re: LNB - Mono/Dual feed & motorizzato
Si, posso vedere tutti e tre i satelliti ma sul 19.2E c'è ben poco in italiano, un solo canale, quindi lo trovo "inutile".
If so you could use a 80cm dish
Ho una parabola da 85cm, una Fracarro Penta.
Adesso ho un singolo LNB con due uscite per due calate. Meglio due singoli LNB con adattatore oppure un LNB dual feed monoblocco?with a 4 way diseq switch with normal single lnb's,
E' più costoso, laborioso e comunque dovrebbero essere più che sufficienti 2 satelliti, il 13E principale e il 9E, non ho grosse pretese.or even better use a motor with the 80cm dish.
Io metterei come principale il 13E e offset il 9E. Esiste uno switch con 2 uscite per due calate? Casomai con 2 IN e 2 OUT?
Grazie!
Re: LNB - Mono/Dual feed & motorizzato
So you are saying, you have two receivers, and wish to receive channels from two satellites 9e/13e.
Best way to do this, would be to get two dual output lnb's, two, two way diseq switches, 80cm dish and bracket, then you will have a down lead from each switch to each of the receivers.

Re: LNB - Mono/Dual feed & motorizzato
Corretto, ho due ricevitori, un MySky HD con dual tuner, che sfrutta l'Unicable SCR per registrare e contemporaneamente vedere un altro canale, ed un GTMedia V9 Prime con singolo tuner.
Vorrei utilizzare principalmente il 13E ed eventualmente anche il 9E.
Grazie, ottima idea; così ogni calata rimane indipendente dalle altre.Best way to do this, would be to get two dual output lnb's, two, two way diseq switches, 80cm dish and bracket, then you will have a down lead from each switch to each of the receivers.
L'unico dubbio è se prendendo un nuovo LNB con output diseq se è compatibile con l'attuale LNB Unicable SCR che ho già installato. Devono essere entrambe diseq per essere collegati allo stesso switch? L'Unicable SCR è compatibile diseq?
Oggi ho due calate; stavo però pensando prossimamente di portare la presa satellitare in una terza stanza. Quindi casomai acquisto un LNB a 4 uscite per poter aggiungere successivamente un terzo switch per la terza calata. Avrei inoltre la possibilità di aggiungerne una quarta in futuro.
Re: LNB - Mono/Dual feed & motorizzato
If you are thinking of going for a third receiver, it would be best to get Three, 2 Way Diseq switches.
Most diseq switches come with covers, with the switch pushed up inside, held in place with (cable tie)(tie-wrap) behind the dish, then the cable from the switch to the receiver.
With the (unicable scr) lnb, how many outputs do you have, if your (sky) receiver is anything like the ones that are used in the UK, they DO NOT like diseq switches, depending on the outputs, you could use the second lnb input.

Re: LNB - Mono/Dual feed & motorizzato
Perché un 2 LNB INPUT e 4 RECEIVER OUTPUT non va bene?
Questo sottostante ha pure l'ingresso per l'antenna terrestre, quindi sullo stesso cavo sarebbe possibile poi ricavare sia il satellite che il DVB-T!
Grazie, saluti.

Per la terza calata al terzo receiver dovrei quindi aggiungere un terzo diseq switch a 2 vie?

Re: LNB - Mono/Dual feed & motorizzato
I am not sure how the (MS34EZ) works, maybe looks for (H/V).
Let's hope Owen see's this thread, he will be better, to explain how this switch works.
For your third (drop) as you say, you will need another 2 way diseq switch.

Re: LNB - Mono/Dual feed & motorizzato
There are three inputs, one Satellite at 13V Vertical, another DVB-T and the third 18V Horizontal and mixes it for the 4 outputs
Re: LNB - Mono/Dual feed & motorizzato
Hi
The Unicable LNB should be able to supply 8 set top boxes, each with a different IF frequency allocated.
Each box then only needs a connection through a standard splitter to connect.
The issue will be if you then add extra standard LNB / dishes that need a DiSEqC switch.
I have not used a Unicable LNB, but I would expect it to work through a DiSEqC switch port.

Re: LNB - Mono/Dual feed & motorizzato
There could be another way around to do this, but it will mean another cable run to your (Sky) receiver.
With the (Sky) receiver been a Twin turner, one cable from the 13e, then another cable from 9e.
Then on the V9 use the (2way diseq), then when you want to add another receiver, you would then use the second (diseq) switch.
Using your 80cm dish, purchase a bracket, (or make one), 2 quad lnb's, 2 2way diseq switches, good satellite cable, connector's, hope for a good day, with lot of patience, (that is if the wife will let you), to carry out the update.
Are both lnb inputs in use on your (Sky) receiver, depending on answer, there could yet be another way.

Re: LNB - Mono/Dual feed & motorizzato
Da quanto ho capito io Unicable SCR dovrebbe supportare solamente 4 set top boxes.
No, il decoder MySky HD utilizza un unico cavo/calata.
Attualmente ho solamente 1 parabola (disco) e un LNB con doppio output. Da quanto ho capito mi serve un altro LNB con doppio output e poi collegare il tutto con il seguente schema:
Code: Select all
____________ ______________
LNB 13E (Unicable SCR)---->-| SW02Q | | |------> Calata MySky HD

Re: LNB - Mono/Dual feed & motorizzato
Your switch "SW02" is a 22kHz switch.
The commands to the Unicable and DiSEqC LNB's use the 22kHz tone to send the commands in a digital format.
This means that the 22kHz switch will change port with every bit of the digital command.
Also universal LNB's use 22kHz to change between the lower and upper bands, 9750 lower and 10600 22kHz "on" for upper band, so a 22kHz switch can not be used before a universal LNB as well.
If the 9e LNB is a multi satellite LNB ( two or more heads) and uses DiSEqC to change between the satellites, that will be DiSEqC 1.0
This will mean you can not use a DiSEqC 1.0 switch in place of the 22kHz tone switch you showed in your diagram.
You would need to use a DiSEqC 1.1 switch, typically a 8 port switch.
If the 9e LNB is just a standard LNB then you can use a DiSEqC 1.0 switch in place of the 22kHz switch.
Note also from your diagram that if one box is using H polarity the other boxes can not use V polarity on the standard 9e LNB.
Also if the 9e LNB is a universal for lower and upper band, any box that is using the upper band will have the 22kHz tone "ON" and that will block all other boxes from using and 22kHz tone commands to the switch or the unicable LNB.
Also if one box changes the replacement of the 22kHz switch (SW02), a DiSEqC switch and another box changes it back, there will be a continued fight and no box will see any channel.
As the Unicable LNB will supply 4 boxes, share that through the splitter you show and then have a DiSEqC switch at each box to a splitter on the 9e LNB.
That will allow no clash between boxes for the unicable LNB and some managed sharing of the 9e so a user on high band or H polarity does not prevent other users form V or lower band.
The better solution then is to add a "MS34EZ" as you showed earlier in this post, but that will still not solve the upper / lower band issue, just the V / H and you would need a two output LNB.
There are 4 output LNB's with a port for 13v 0Hz, 13v 22kHz, 18v 0Hz, 18v 22kHz and switches the same, both powered and unpowered.

Re: LNB - Mono/Dual feed & motorizzato
Can you show a few photo's, of your (sky) lnb's menu's, i am hoping that there is a Universal setting of (9750/10600).
Plus with you saying you only have one lead to your (sky) receiver, the best way to get full use of the system, would be to remove the (Unicable SCR) lnb, and fit two quad (Universal) lnb's, one lead from the 13e direct to the first lnb input, one lead from the 9e direct to the second lnb input.
Then using the diseq switches, placed behind the dish, then the leads from them down to your other receivers where you would use the (1.0diseq) setting.

Re: LNB - Mono/Dual feed & motorizzato
Non sono a casa per mandarti i settaggi di MySky HD; ti mando i settaggi del V9 Prime.
Corretto, attualmente ho unicamente un solo LNB puntato sul 13E con parabola da 85cm con uscite e due calate, una per il ricevitore MySky HD e l'altra per il ricevitore GTMedia.Plus with you saying you only have one lead to your (sky) receiver
Il dubbio principale era appunto se aggiungere un secondo LNB per il 9E, se optare per un LNB monoblocco dual feed, oppure addirittura passare direttamente ad un motorizzato. Se è necessario sostituire il 13E basta solamente che questo sia compatibile con MySky HD.the best way to get full use of the system, would be to remove the (Unicable SCR) lnb, and fit two quad (Universal) lnb's, one lead from the 13e direct to the first lnb input, one lead from the 9e direct to the second lnb input.
Vorrei aggiungere una terza calata, eventualmente in futuro una quarta; Calata 1 soggiorno (MySky HD), calata 2 studio (GTMedia V9 prime), calata 3 cucina (GTMedia ???).
Da quello che ho capito se mettessi un motorizzato sarei vincolato alle scelte del ricevitore master che decide su quale satellite puntare, gli slave non sarebbero indipendenti.
Considerando che il motorizzato è più costoso e vincola i ricevitori slave, io utilizzerei solamente il 13E ed il 9E, quindi opterei per un dual feed fisso.
Gli switch posso anche metterli nel sottotetto, al riparo da pioggia ed umidità. Ovviamente se metto due LNB con 4 uscite dovrò portare nel sottotetto ben 8 cavi.Then using the diseq switches, placed behind the dish, then the leads from them down to your other receivers where you would use the (1.0diseq) setting.
Immagino che tu indichi uno schema di questo tipo:

Non c'è quindi modo di fare un unica calata dall'antenna e poi utilizzare uno splitter a valle quindi?
Usando uno splitter è come un duplicatore ma non permette ad ogni singolo ricevitore splittato di decidere quale LNB utilizzare e con quale polarizzazione, corretto?
Switch 2x1 A/B/C/D
Grazie, saluti.
Re: LNB - Mono/Dual feed & motorizzato
Best to bin the (motor), going for diseq would be best, depends on the lnb settings on your (sky) box, plus it would be cheaper.

Re: LNB - Mono/Dual feed & motorizzato
From what i have read the (Unicable SCR) only works with receivers that support (Unicable), one of which is the GTMedia V7 Pro. (Unicable 2.0).
I DO NOT know the full workings of that system, from my other posts, i know that using Quad Universal lnb's and diseq switches work, because i have a few dishes, going to Two receivers using diseq switches, and i know that it works, (39e/28e/9e/30w).

Re: LNB - Mono/Dual feed & motorizzato
Sto utilizzando l'unico LNB presente sia con MySky HD impostato come SCR sia sul V9 Prime impostato come l'immagine che ti ho inviato e funziona perfettamente con entrambe. Quindi anche il V9 Prime supporta l'Unicable SCR. Col nuovo fw Mars addirittura l'impostazione è più semplice, non con le frequenze come sul vecchio fw della foto, ma con Unicable SCR con le 4 impostazioni (A/B/C/D).
Questo sottostante dovrebbe andare bene senza alcun switch e notevolmente più semplice da montare; confermi?
Altrimenti un paio di questi sottostanti con 4 switch 2x1.
Quale adattatore per distanziare i due LNB mi consigli? Come si fa a misurare che siano distanti 4°?
Re: LNB - Mono/Dual feed & motorizzato
By the look of it, you have found the correct (Monoblock), 4 outputs, on the GTMedia receiver, you may have to amend the diseq setting 1.0 against each satellite, 13e @ 1 / 9e @ 2. Not too sure about the (Sky) receiver, you will have to check the LNB settings.
When fitting, it will be bit of trial/error, you may gain some signal from 13e and loss some 9e, then move the mono block a little up/down you then gain signal at 9e, then loss some signal from 13e.
For me, i can adjust my dishes with ease, been near the ground, using a portable TV, step ladder, i can make adjustments, and see this on the screen, then tighten the nuts/clamps etc.
Keep us updated.

Re: LNB - Mono/Dual feed & motorizzato
Check the specification for that 4 degree mono block for the dish size?
That they work for satellites in the sky at 4 degrees would also depend on the dish size to match that 4 degree spacing.
If you put that mono block on a 600mm dish it would not "see" the same angle in the sky as if put on a 900mm dish.
There should be a specification saying what dish size this mono block is designed for.
This design with the splitter before the 8 way switch will mean only one box can control the switch.
Each box needs its own switch and then splitters to the ports on those switches.

Maybe a splitter like this one.
