Sky Q distribution around house via HDMI modulator

[P1stonbroke]

My current SKY+ HD box distributes signal via RF out throughout my house via coax to a powered splitter in the loft and then to  other tv sets, each additional TV having a TV eye .  Works extremely well but now having to replace current SKY + box with Sky Q which of course does not have RF output.  In simple terms, will using an HDMI modulator connected to the new SKY Q box and then using the RF output on the modulator to the existing coax system, still provide a signal around the other TV sets.  Thanks

@P1stonbroke  This Triax modulator is a typical example;

Hi I have a similar issue

I am currently a SKY HD+ user and use the RF2 output to distribute both Freeview and Sky channels to a distribution unit in the loft.

It is an 8 way distribution unit and feeds 5 other TVs in various rooms.

I have received an email stating my SKY HD+ box will no longer be receiving and offering a SKY Q box for no installation cost.

I understand that Sky Q box has no RF output.

The question I have is if I elect to install a SKY Q box how will I be able to distribute both Freeview and Sky channels to my distribution box.

I have seen from previous posts that the use of something like an Edison AV modulator or this Triax modulator can be used to distribute the signals but will this distribute both Freeview and Sky channels through the modulator to the distribution box?

From the diagram my understanding would be that the Sky Q box would connect to the Triax and not the TV.

The Freeview aerial connection would connect to the Triax box as well.

There would be a HDMI out cable from Triax to TV to carry Sky signals from Sky Q box.

The RF1 out would be connected to the TV for Freeview channels

The RF2 out would connect to the distribution box in the loft.

Would the RF2 out signal carry both the Sky signals and Freeview signals as part of the same signal?

Which is the best AV modulator to use for distributing the signals?

I ised to have 4 SKY+HD boxes in a sytem like yours.  Then i was uograded to SkyQ. They now dont call SkyQ an upgrade becaus eit isnt.  The biggest trouble toull have is cost Q is UHD and UHD  Modulators are expensive and theres alot of blocking going on.   My current set up Is the main Q box to the main TV ans a Sky mini (which are HD only) plugged into a new HD modulator into  my existing setup i also upgraded my CCTV modulator to HD at the same time.  Bewarned ijf you have old TVs that dont have DVB-T2 modulators then they wont pick uo the channel of the HD modulator.      Look up DVB-T2 modulators in your online shopping site but your looking at £150-200 per box. And there no guarantee on how long they will be compatible (HD only remember no 4K)

@Pogit @Keith69. 

I've replicated the Sky+ output on a Sky Q  box which doesn't have UHD (4K), only HD (1080p).  I used a Hemer HDMI splitter (from Amazon £8.99) to send 1080p to both the TV and a Dpofirs AV modulator (Amazon £42.23) which converts 1080p to Analogue TV,, the same as Sky+ used to do. If it's Sky Q UHD, then you need a splitter which sends 4K to the TV and downgrades  the 4K to  1080p to send to the modulator.   Try the ezcoo 4K HDMI splitter (Amazon £29.99).  I've got this working on a BT TV UHD box.

@Sharky1.  I forgot to say, you need to splice the Dpofirs Analogue output into the TV aerial signal before it's sent round the house.  The Sky+ box used to do that. It's easy to do, you could use a y- connector although I prefer to use F-connectors with a cross piece (Amazon Poppstar 2 for £5.38).

Another potential product

[Sharky1]

@ChodleyYes, I looked at this but this is a DVB-T modulator.  It outputs a full HD 1080p Digital TV channel which needs all receiving TV's to be full HD.   All of mine are just HD-ready, so I just wanted a solution which replicated what Sky+ did.   I've even got it broadcasting on the same analogue channel the old Sky+ box used.   It doesn't provide 9v Infrared-eye support because the Sky Q zapper is Bluetooth, and my zapper works all over my house.

[Keith65]

Thanks Sharky1 sounds promising.

So if my understanding is correct are the connections and diagram below correct? If not what is wrong. 

Does the Sky Q box have a HDMI in and out connection and which woudl be used?

You say thet SKY Q "zapper"/control is bluetooth and can be used from anywhere in the house so this negates the need to use magic eye IR connectors?

[Chodley]

Bluetooth range is limited so  ...maybe. Actually also means an IR magic eye compatible with SkyHD won't work. Also they relied on sending signals back down the cable to the main box and with no RF2 out on the Q...

The Q has HDMI Out only. Not sure why HDMI In would be needed?

[Pogit]

Sky Q Bluetooth remotes have very limited range and are now restricted to one remote per box (previously could have atleast 2). The technomate RF-ID can receive and send IR signals from multiple locations to the main Q box, but it's much easier to use sky Q remote or a remote app that sends controls via Ethernet/wifi to control boxes from another room.  *note all distributors introduce a delay which can be a pain when controlling boxes

@Keith65 In theory your diagram ought to work but when I was first playing with the Dpofirs box, I found that it didn't work very well at passing through Digital TV aerial signals. I thought this might be because it's from the analogue TV era.   Therefore I've got the TV signal 4-way splicer joining the aerial input to the Dpofirs output, the TV and the Distribution box.  I don't have anything going into the Dpofirs Antenna In socket.   Bear in mind, aerial signals aren't actually directional, they're just voltage levels the same at every point on a wire.  I guess in theory, the Dpofirs box would amplify the Antenna In signal on the way through whilst modulating it with it's AV output, but as I said, I found it distorted it.   I messed around a lot in the early days, and when I got a working system, I didn't bother going back to try things again, so if you get your configuration working, let us know.

@Keith65 I forgot to mention I've got a mast-head amplifier on my aerial, this probably helps in bypassing the AV box pass-through amplification.
