Satellite & Virgin media broadband

multisport

Apologies if this should be in a different board.

At the moment I have Virgin media broadband/tv/phone but I'm looking at dropping the tv part of the package and getting Sky instead.

Is it possible to bring the two signals (broadband and satellite) into one cable and then split them again.

I've seen some combiners for terrestrial and satellite feeds but will that work on a broadband and satellite feed too?

If this isn't possible, it's not the end of the world, it just means I'll have a cable coming down the wall instead of being neatly in a conduit under plaster.

Thanks in advance,

No, under no circumstances can a satellite and cable feed be combined.

Sky Q will be expensive depending on package needed,have you checked the sky threads for feedback?

Is there a technical reason for that, given that analog and satellite can be combined and then split?

Broadband will come from a router

SkyQ works differently to the previous versions of Sky. SkyQ uses wideband technology to send the feeds from the LNB to the receiver.

Wideband technology spreads the intermediate frequency from the LNB to the receiver across a wider frequency range which now overlaps the terrestrial frequency range, this prevents SkyQ and terrestrial/cable sharing the same cabling.

Legacy I.F. range 950-2150 MHz
SkyQ I.F. range 290–2340 MHz

Terrestrial frequency range 470-694 MHz

The Cush, thank you. It might be a technical answer but I understand it and it's what I was looking for.

The inference in that answer that suggests non-sky Q legacy satellite feeds can be combined with cable is absolutely wrong.

Analogue cable and UHF terrestrial could be combined in the past but only on the downstream side of the cable termination filter, combining upstream or without the filter was always one of the causes of network interference and back in the days the cable companies had their own engineers a very dim view was taken of people doing that.

Terrestrial TV and cable feeds are completely different. Cable has always used a wider range, even when it was just carrying analogue TV. These days it has to carry extensive digital tv muxes as well as two way internet traffic.



At best combining a satellite feed with the cable coax will just not work, at worst you could be killing the cable network for yourself and your neighbours. In newer networks each house will have a dedicated coax to the local fibre headend, in legacy areas many properties share a pair of trunk coax lines.

Any amount of "signals" can be transported in one conductor designed for such.
the issue here which i do not see addressed is ==== latency =====.
a sat dish to transmit and receive "internet" takes longer than
a terrestial cable.
albeit with ireland a cable shows home to european mainland ip address is 23ms
to eirs hardware and their loops 19ms by traceroute and 4 to ip addresss.
such a farce from my point of view.
a sat signal to sat and back will take longer as distance traveled and also there
may be atmospheric conditions that have an effect aswell.
basic school stuff of "turn on light switch" signal create a wave that circles the planet at 7
revolutions per second and fades shows the physical conductor is faster. atoms and light(fibre).

lnb to receiver is an electrical current at amps- at a certain frequency.
tell me how i2p works with tcp as that is as transport on a conductor.(its an overlay and causes no interference.)
as was stated ==== years ago tech had problems with inter frequency interference but
we have moved on.
the atoms and directable electrons that can be "streamed" in a 1mm\sq copper conductor ?.
seems you talk away from the likes of 625Mb tunnels in a cable with each only able to carry
limited certain signals.
as eir uses brittelco you point at cables the size of londons underground sewerage works tunnels.
cmon mate over 20kms 5g from one tower and the advertised capacity must make you think.
yes 2 towers cover dublin and forget the green footprint issues of miles of cables which the
green party dont seem to mind. of course not allowed to use cheapest most reliable chinese
but thats corrupt politicians for you.

Why broadband is split to the router one side of splitter to router and other side to cable box.


I do know of combining a saorview signal and a sat signal with a diplexar through one cable and extracted the far end:D

If you combine both SkY and Virgin wash their hands on any support issues.

An easy excuse is to blame the other provider

I've made my decision now, I'll stick with Virgin for broadband, and run a separate cable for the dish, no crossover at all between the signals or providers.

When planning out your sat try to plan ahead as if sat has a sky Q lnb it can only be used for sky Q boxes,hybrid lnbs are available for E2 boxes.

How many cable feeds will you use as best to install 2 at least for viewing and recording and another room? quad lnb.

No issues using Virgin broadband and multiswitches around the house to give more lan ports if needed and all hard wired.
