I have previously bought 2 Gigablue Trio 4k boxes from sponsor.
I'm now looking to upgrade the third (main room - currently sky+ hd) box to a Gigablue UE 4k.
There is currently 2 (28.2 astra) satellite cables(for UK tv) in room, alongside 1 aerial Saorview(Irish terrestrial DVB-T) cable (for Irish channels).
The Irish channels are split across 2 muxes.
I was hoping to buy https://www.world-of-satellite.co.uk/gigablue-uhd-ue-4k [2xDVB-S2X FBC (8 demodulators) + SPARE TUNER SLOT] and have the spare tuner slot be DVB-T/T2 tuner.
Will the 1 aerial Saorview cable going in to the back of the box still allow viewing/recording across the 2 muxes at the same time using https://www.world-of-satellite.co.uk/gigablue-dvb-c-t-t2-h265-twin-tuner-module ? this seems to have 2 cable inputs on back(instead of internal loop etc.)?
No you can't access 2 multiplexes with a single tuner.
For your use I would consider the Vu Duo 4k SE with DVB-S2X FBC in slot 1 and DVB-T2 twin in socket 2.
It is more money but exactly what you need.
If you by a box without sufficient internal tuners you will regret it.

That tuner picture is not very good. It is the twin tuner unit, so you will have access to two multiplexes. It has one input and one loop out. But you will have to wait for stock to be available.

It has one input and one loop out. .
Is the loop out just to daisychain other devices?

I looked at the Vu Duo also but keeping all the remotes the same layout etc.. has value for my folks.
> sufficient internal tuners
The 2 sat lines (connected to non-unicable lnb) connected to 2 FBC inputs should cover me.
It's just the 28.2 astra satellite so my understanding is unicable lnb wont really add that much value to my setup(for the main room box). Willing to upgrade to unicable lnb in future if needs be.

It's potentially my replacement machine when my GB Quad Plus dies. In Ireland, you definitely need a dual DVB-T tuner and dual DVB-S tuner setup to cover the local Saorview/Freesat environment.
You can easily split the Saorview signal using a cheap splitter.
So you will end up with 2 sat feeds and 2 terrestrial feeds feeding 2xSat Tuners and 2xTerrestrial tuners.
That will give you what I want, i.e. the ability to watch any channel and record another at the same time.
I have the H7S with one Saorview tuner and have the splitter to feed the Saorview tuner in tv so if i need to record i use the box and can view others on tv .
Very few channels we have that we need twin tuners for Saorview.
Just a thought.

No problem splitting the signal feed. The issue is the number of tuners.You can't record RTE1 and RTE2 at the same time.

Even with the twin tuner module the OP posted a link to?

Yeah, that was my plan but i think the linked twin tuner which abu said has 1 input gives me the same solution.
I already split the saorview by 3, then use a combiner to send 1 sat and 1 aerial down the existing line and split at the other end(saved me from having to run new wires - different frequency ranges so there's no overlap). I did this for the existing 2 giga trio boxes i have.
The box is for the main tv room so happy to spend the €€ needed to get a decent one that has same/better functionality than sky+ box we have.
If needed, i'll upgrade the sat lnb to unicable but i think i may be ok without.
Yes the Vu Duo 4k SE twin tuner has a single input so would give you a slightly neater setup.
You would be looking at nearly doubling your costs though and getting very little extra for it

Based on Abu's comment, this is how the Gigablue UE also works. The 2nd connector on the linked tuner is a loop out connector.
Hopefully someone who has the gigablue UE box with 'DVB-C/ T2 (H.265) Twin tuner' will chime in with definitive answer.

No - with the single tuner. @cactikid referenced feeding the box tuner with one lead and the TV tuner with the other feed. I almost never watch live TV, recording anything I want to see so need two tuners on DVB-T. The twin tuner is ideal and would let you record from both multiplexes. See post #7.

I have the GB UE 4K. Like most other twin hybrid tuners, it has one physical input.
While there is no stock of these tuners discussion is academic.
I just checked my own setup there which is a Gigablue UHE UE 4k and additional DVB-C/T2 twin tuner. This one:
https://www.world-of-satellite.co.uk/gigablue-dvb-c-t-t2-h265-twin-tuner-module?search=gigablue%20uhd
The DVB-T twin tuner is being fed by a single cable and I was able to record about 6 channels simultaneously just now no problem.
So it seems you could connect a single physical cable feeding both tuners
On the same mux or different ones?
On the same mux or different ones?
Based on the Saorview Wiki page, it looks like there are only two Muxes.
The six channels I selected definitely cover both muxes
On the same mux or different ones?
The one cable is feeding both tuners internally. Each tuner is receiving and demodulating the signals from a separate mux. There are only two Saorview muxes.

I ended up going for the only option available, the pricier VU+ Duo 4K SE.
Gigablue have no stock(seemingly noone does) and no intention of bringing out more of the twin dvb-c/t2 tuner due to lack of chips.
Ah well!
Sky got the bullet today so that offsets the cost somewhat.
I'm sure you are going to love the Vu.
