Combining dvb-s and dvb-t signals

[Le Vette]

I have three holiday lets in France and I want to combine the signals from a single dvb-t terrestrial antenna and a single dvb-s satellite dish (both on the roof). Ideally I want the combined signals to go down three individual coax cables (one into each property) so that I can either have French TNT tv (dvb-t) or Freesat (dvb-s) at the TV end (with either a Freesat box or a TNT box) and switch between them independently, depending on whether we have British or French guests.

Does this make sense, and do any of you wise and wonderful techie types know if this is possible and if so, what gizmo would deliver the solution I need?

This is basically what I'm trying to do:-

Something like this would do I think although a tad expensive:

a multiswitch would do what you want, but you would need a quad lnb and 4 coaxes from the dish to the multiswitch, then a diplexer in each flat to split the terrestrial from the satellite.
try to open an account with solutions group impact and they will supply you with everything you need.

Thanks.... Do you have a link for solutions group impact please?

Many thanks... I've sent them a message to clarify how this solution should work.

Dish with either Quad or Quattro LNB
4 Coax, from dish and feed from aerial to this

Single coax to a socket like this

Make sure that if you use a multiswitch that you get the right LNB, some work on a Quad some work on a Quattro, if you use the quattro you must get the polarities wired correctly. Easier to use a quad lnb and a compatible muti switch
Make sure you buy diplexed face plates, dual outlet ones require 2 cables not one.

The stuff I have linked to will do the job, I have no link with the sellers etc

How did you solove the problem?

Solution (yet to be proven, in fairness):-
A) 3 outputs taken from satellite LNB.
B) the cable from terrestrial antenna is split into three using a splitter.
C) One LNB cable and one antenna cable is input to a combiner (in the loft).
D) Repeat 'C' twice more.
E) Each of the three combined cables is individually routed down to behind each of the 3 TVs.
F) At each TV there is a diplex combiner wall plate which separates the signals back into sat/terrestrial.
G) From the wall plate one cable goes to the antenna input of the decoder and one to the satellite input of the decoder.
H) It is yet to be confirmed if one decoder can display the full set of terrestrial channels and the full set of Freesat channels at the same time, but if I need 2 decoders at each TV then that's what I'll do.... necessary bits are all on order.

I'll update this once I've got the bits and proved that it all works as anticipated...
