Sky Q (dual cable) from Dish to Box via Single F-Type Connector ?


Recommended Posts

Hi

 

Is it possible to combine a Sky Q dual feed to be sent over a single cable (using the single F-Type connector and cable in my van) and then split out the dual signals at the Sky Q box end?

 

I am thinking of something like a 2 into 1 then 1 into 2 setup if that makes sense? 

 

Would rather avoid changing the single cable to a dual cable, so I can use the setup in different vans.

 

Thanks

 

Phil

NO. The LNB has in effect the same number of separate receivers as it has connectors, i.e. two connectors = two receivers. Satellites send the signals down in the frequency range 10.5-12GHz or 10500-12000MHz in old money which will suffer significant loss on the cable between the LNB and the sat box. This is down-converted into a frequency range of 950-2000MHz which has significantly less loss on the same cable type. They also have vertical or horizontal polarisation (like your TV aerial might have its 'prongs' vertical or horizontal.)

 

Satellite signals are down-converted into two frequency bands to send down the cable. The box - whatever type - sends a 22000 cycle whistle up the cable to switch between the two frequency bands; it normally sends 13V or thereabouts to power the LNB - this is increased to about 18V to make the LNB switch polarity.

 

Each station being transmitted by the sat uses a fixed frequency and polarity. Your sat box 'knows' what these pairings are and sends the appropriate pairing of whistle and voltage to get the station you want to watch. If you look at this page Lyngsat it shows down the left column the frequency and polarity that is needed for any given station. Note that this table is related to Astra 2G which can be received in the UK and RoI but not much into Europe: some Sky stations come from Eutelsat which have a much bigger footprint that can be received over much of Western Europe. Look at the maps on the same web site.

A Stacker / destacker system may do the job, where you put the two feeds from the LNB into a stacker, then the single cable down to the tv location, where the destacker splits the single cable into two cables again.

 

But i have not used one on SkyQ before, only Sky+HD, so dont know if it is SkyQ compatible.   Or look at a dSCR LNB and put the SkyQ box into dSCR mode (again not tried this so cannot say if it works or is what you want)

The European beam, that carries the majority of Sky pay channels is easily available around Europe.

It is the UK beam, that carries the likes of BBC, ITV, C4, Fives, UKTV; Discovery, BTSports, that is weak around a lot of areas in Europe.

No "Sky stations come from Eutelsat" as the Eutelsat satellite that was at 28 east was moved away a few years ago now. Current UK TV satellites are Astra 2e, 2f and 2g.

Nope.  That how an old Universal LNB works frequency wise-ish.

 

$ky Q uses a Wideband LNB.  That has one Horizontal outlet occupying 290–2340 MHz and the other Vertical also 290–2340 MHz.  Note the low frequency down to DAB (almost) and higher than the universal lnb IF goes.  Local oscillator is 10.41 GHz according to Wikipedia for these wideband lnbs.

That will work and is how $ky do it as single cable for Communal installs of Q.  Needs a new LNB on the dish, of course.

 

Stackers-destackers would have to be specially designed for this specific wideband LNB use... Older ones will have the wrong filtering.
