Advice Needed SAT+DVB+DAB setup in new home

[local system user]

In my new home I have a single coaxial cable heading outside from the wall box where it meets coaxial cables running to TV/Radio sockets installed in all rooms. I am planning to install DAB, FM, DVB antennas using triplexer/combiner and satellite dish with two LNBs attached to splitter or diseqc switch. What I need is advise that equipment to use to make it working properly.

As a triplexer/combier I'd like to use for instance:
https://cpc.farnell.com/optima/114212/outdoor-fm-dabuhf-tv-triplexer/dp/AP03518

Then for satellite LNBs:
Twin 4-feed LNB for 9°E, 13°E, 19.2°E and 23.5°E for 80cm dish
+ another one to cover 28.2+28.5 positions.

What should I use to combine/sum the triplexer with satellite signal and be able to watch tv from two different satellite positions?
MFD 411 DiSEqC 4Sat+1Ter x1out ?

Also is it possible to cover 28.2 and 28.5 with single LNB converter assuming 80cm dish? I am aware about the 7 degree skew difference between 28.2 and 28.5.

What should I use in the cable box at home to distribute the signal?
Please take a look on the attached picture.

28.2 & 28.5 are close enough together that you dont need to worry about them - one lnb will "see" all 3 satellites operating at the two 28E slots absolutely fine on any normal domestic dish.

TA, what about my other questions?

Are you planning on installing the mono and normal lnb on the same dish?

I think the simplest way would be to run the satellite systems separate to DVB-T/DAB distribution. Each satellite system would need a DiSEqC 1.1 switch to switch between the Inverto monoblock and the 28.2°E LNB.

If you can only use a single coaxial cable from outside it's going to be more complex to allow the separate satellite systems to operate independently.

Yeah, probably using this dish: Technomate 80cm Mesh Satellite Dish Kit with this bracket: Technomate Triax Multi 4 Way LNB Holder bracket

So there are no smart diseqc switches to allow this (or anything else I could mount maybe at home)?

A stacker/de-stacker system may work if it allows DiSEqC signals to pass.

The problem is to provide two TVs with several satellites with a single cable coming from outside.
For me you must have at least 2 cables that enter the house.
with this solution you will have to spend a lot on coupler, decoupler.
With 3 cables you reduce the problems and the overall cost.

Any particular model:

JOHANSSON DiSEqC Stacker / De-Stacker from Alltrade

GLOBAL DiSEqC Stacker / De-Stacker

Where this should be plugged-in: diseqc -> stacker -> cable to home -> de-stacker?

 

[ozumo]

The PDF file linked to on the Johansson stacker page suggests it does pass DiSEqC signals.

LNBs output 1 -> DiSEqC 1.1 switch -> triplexer/combiner with DAB & DVB-T inputs -> Stacker
+
LNBs output 2 -> DiSEqC 1.1 switch -> Stacker

This would then have one coaxial cable entering the house. The de-stacker has two ouputs, i'm not sure if they both carry DVB-T & DAB, if not the de-stacker output that does could be split and then run through a diplexer and then the TV & radio combined with the other de-stacker output. Then split that into two and send one to the room that does not require satellite.

You'll have to drill to mount the dish, switches, stacker etc so for the sake of a simpler system drilling an extra hole for a second coax would be preferable IMO.

Do I understand it correctly that you want to watch/hear always just at one location at the house, so nothing simultaneously at your three locations?

Otherwise, when you really want just one cable coming in through the wall, it will be much more complicated.
5 satellite positions, DAB and DVB-T, for three receiving locations, maybe also extra recording wishes or 'multiple tuners'?
Receivers being able to handle diseqc x.1, or diseqc x.2 (GotoNn)?
Receivers being able to handle Unicable/JESS?
You absolutely still want no other cables through the wall?

Far too limited info for me, till now, to advise anything sensible.

it's not the only expense, you also have to inject the "DVB" and DAB...

I do want to be able to watch from two (only) different satellite positions at the same time but rarely. Third (fourth and fifth) location can be DVB/DAB only.
I don't need to record anything,
I don't have any tuners yet, so advise here will be welcome. No preferences in terms of diseqc 1.x or 2.x. I just want to make it working if possible.
Ideally I don't want to provide any additional cables. I may consider having just one satellite receiver only with two LNBs as mentioned above if what I want is impossible to achieve.

More I am looking on stacker specs more I am convinced they can't carry dvb/dab signal despite they support 5-2150 MHz / 950-2150 MHz on stacker input. Am I right?

The 5-2150MHz output will carry DVB-T & DAB. Look at the example system setups in the PDF manual or the image in post #13.

Perhaps shotgun cable will work. It is two smaller cables combined that fits through one hole. Then you just need two combiners and DiSEqC switches outside. However I don't know if shotgun cable is up to the job.

I fitted a satellite system for some friends down in the Vaucluse last August after they had moved house. There was a fair amount of ready installed cable around the house but unfortunately only single cable to each room. I tried, oh boy I really tried, to pull two regular PF100 cables through to the living room for the satellite PVR but just couldn't get the pair past the last 90 degree bend of the embedded flexible hose (gaine).

I then bought a stacker/destacker system which disappointed me as it attenuated the signals too much. I finally used double CT67 "shotgun" cable. It lost less signal than the stacker/destacker and works - mostly. In this case the house terrestrial aerial was pointing off direction and I wasn't able to access it to turn it round (too hot, too many wasps) and could only put another aerial in the loft space. This was all fed, together with the output from a Quad LNB, through a multiswitch and then piped out.

If you have enough signal for the stacker/destacker then ISTR that only one of the stacked bands is wide enough to include terrestrial signals. If you want terrestrial signals down both leads then this will not work for you.

I still have the stacker/destacker around somewhere and really must get around to selling it sometime!

When you want to watch from just one receiver at a time, you could have 64 LNBs outside to switch to, with diseqc x.0 and x.1; or even more when you also use diseqc x.2 switches. And priority switches inside, when you have more than one receiver. Just one cable is no problem, then.

Multiple receivers simultaneously/independently, that is where the challanges arise when you want to have only one cable through the wall.
- Stacker/destacker: Cable attenuation because of the high frequencies is one thing (see above). [And I'm not sure if diseqc commands for more than 4 LNBs (so: more than diseqc x.0) are supported in the modern devices?]
- Modern solution for just one cable would be Unicable/JESS, usefull for multi-receiver setups. Your receivers would need to support that (modern receivers do). But multiple Unicable LNBs or a Unicable multiswitch outside will make things more complicated and expensive. And possibly needing an extra power inserter. And not all receivers support LNB-switching for Unicable, or just support switching between two LNBs, I believe.

And does just one cable through the outside wall mean also just one cable for sat and DAB/DVB-T combined from each receiver to the "box" in your drawing? That might also be a challange, as you might need extra diplexers there. All this diplexing will cause a bit of signal deterioration.

I assume your dvb-t and dab antennas are going to be passive? Or do they need power?

So, given the possibilities and impossibilities, and advantages and disadvantages of several solutions, the choice of what really is important for you is on you...

Edit: I was forgetting the Unicable variant for the stacker/destacker as a possibility, above. Cannot find it quickly on the internet. Don't know if that supports diseqc switching.....
Edit2: It's called Technirouter 2/1 (Technisat) or Dur-Line UCP 21, for example.

Yeah, so there is only one coax cable heading from the box at home to outside. This Technisat Technirouter has optional DC power in, do you know when it might be needed? Also is this router needed to replace the stacker/de-stacker or to work among?
DAB/DVB-T will be passive I can see the Sandy Heath transmitter through my window and can receive DVB-T signal using only short coax cable plugged to my tv with 90% of quality.

In summary I need:
2x LNB -> 2x diseqc (1.x/2.x?) -> triplexer -> stacker and/or router -----> de-stacker and/or router?
What tuners would you recommend, as I said I don't need recording anything but I also don't want something hanging-up or taking ages to switch channels.
