I have split the signal from my satellite dish and now nothing works.
Brian Butterworth published on UK Free TV It is not possible to split the signal from a satellite dish.
If you want more than one signal from the dish, you must connect a quad-LNB and feed a signal from it to each dish

Mark: Just to add, that if your Freesat box is only that, i.e: not a PVR, then you could couple one of the co-ax cables from the LNB at the back of the house to the co-ax going to the front, then at the front couple that directly into the Freesat box, but "not" connected in any way with the Labgear 8 way amp / splitter.
If the co-ax that goes under the house is black, it may well be a Satellite grade cable that's been installed and as such standard "F" plug couplers could be used, but whatever it is there are couplers / adaptors easily obtainable to join practically any sizes of cables together.

Mark you need a proper aerial rigger to come and help you dont try and do it yourself yiu could end up costing yourself more money in the long run. Have you had a aerial rigger out to make sure that you carnt get freeview if you want freesat to 8 points you could try an octi lnb but you need to run a coax from the lnb to each point .

I have a selection of cables running from roof to ground floor ie dab, tv, cable, broad band, ethernet and phone.I would like to join tv, cable and dab into one cable to enter a wall plate outlet.How do I join the cables at source end?

Geoff: I am afraid you have me rather baffled! this because I cant quite understand what makes you consider that cables carrying different types of signals can be joined at any point.
The standard procedure for doing as you require is to use a piece of plastic cable trunking such is used in electrical installations.
If of course you are really meaning joining them together purely as a temporary measure to pull them through somewhere, then this is just usually done by bunching them together and tightly (and copiously) wrapping insulation or duck tape around them after previously having made a loop on the toughest cable before hand before wrapping, this to attach the pulling fish wire onto.

I want to split my sky cable to connect to freesat boxes in two rooms. Is this possible? Reading the comments it looks like it isnt, and that i need to instead connect from the dish. The freesat boxes would never be on at the same time. Do i still need to connect from the dish directly?

I forgot to say that the sky dish is currently unused hence the reason for wanting to make use of it in two rooms.

Geoff: You can combine different signals onto a single coax cable using a diplexer (for two) or a triplexer (for three) etc. BUT you can only do this if the signals don't use the same frequencies.
This arrangement is used in e.g. blocks of flats where only one aerial system feeds a multiswitch which combines satellite, terrestrial TV, DAB and FM onto each coax output. The wallplate each flat contains the filters to separate these signals.
You won't be able to combine cable TV with anything, and likewise with ethernet, so keep these entirely separate.
The telephone and broadband are already diplexed (before any ADSL filters) so normally run in standard telephone cable (again, don't combine with anything else).
N.B. If you have a Sky+ or Sky HD box you'll need two separate coax cables for the inputs (but you could combine with terrestrial TV, DAB & FM).
Have a Google for "multiswitch" and also for "triplexer" to see what options are available.
Bear in mind that there is some signal loss going through diplexers - don't use with marginal signals.

JiggleBob: I have seen an arrangement using a zone 2 dish (bigger) feeding a 2-way splitter (lossy, so needed the bigger dish). This enabled a single Freesat box to be used either upstairs or downstairs with only a single coax feed into the house.
However, in your situation, with two separate Freesat boxes I'd avoid doing that - Sky boxes send volts up to the LNB on the dish even in standby mode - Freesat boxes that I've tried don't (they only send volts up to the LNB when they're operating), but I can't say that's true for all Freesat boxes. You want to avoid the situation where your Freesat boxes are trying to send different voltages to the same LNB.
Best option is to have a quad LNB on your existing dish and separate cables to each room.

Thanks JM, I have routed the wire to one room. Everything works ok. The other questions is, do i need a hd dish in order to get freesat hd? I noticed that on demand tv (iplayer etc) is possible but only on hd boxes. My sky dish is about 8 years old. Do i need to upgrade my dish to get freesat hd? Or can i use any freesat box as long as it has an ethernet cable?

JiggleBob: No special dish is required to receive HD services.
