house wiring option

redzer007

Hi All,

Apologies if the info is elsewhere on the thread, I did look but could not find it.

I am building a house at the moment, and want to wire the sky boxes in a central location and feed TVs from there,

Can some one let me know of a site that will show me the requirements?

wiring diagram and suggested solns if possible, thanks

Are you talking about having the Sky boxes themselves in a central location (away from the TVs) ???

How are you going to use the remote controls to change channel ?

with something like this

just have one in the room, and have it wired to the box via co-ax


there are other options as well, Im more concerned with how Im going to get the picture to the TV over long cable runs.

If you place the sky boxes in a central location you will be losing out on picture quality and stereo sound.

Run cat5 and use a video balun and you can get stereo sound from a central location...


If you are planning to place boxes in a central location, i.e. under a stairways then you should run at least 2 cables of RG6 Grade minimum(Preferably CT100) or equivalent to each room.

Next you need to decide what you will be getting installed and future proof it, I usually tell people to run 4 or more cables to their attic from their central point so that you can get the signal to the central point easily after the house has been build.

For example for Sky + you will need 2 cables, and 1 there after for any additional box and one for terrestrial .....so 4 would be the minimum but I would for future sake run more and also a phonelline....

Will this support RGB or HD video?

With suitable Baluns, and cheap DIY or bought HW you can do Composite, S-video, Component, SCART RGB, & Stereo etc on Cat5.

Slightly more expensive powered balun HW with amp and switch for cable length will do VGA and Component at up 1920 x1200 60fps progressive. Distance shorter at higher resolutions.

DVI and HDMI would need special more expensive adaptors, likely only up to 20m (but I don't know if they exist).

Ordinary resolution video can be fed up to 1km on CAT5 with suitable adaptors / balun.

You can make a set of baluns out of the inside of a pair of TV splitters. Each signal needs one pair of wires (so 4 signals on one cat5) and a balun at each end.

Only 4 pairs in one Cat5:

• Composite + Stereo = 3 pairs
• Component + Stereo = 5 pairs
• S-Video + Stereo = 4 pairs
• RGB + Stereo = 6 pairs (4th is Composite pin used for sync)
• SCART with RGB switch and WS switch + Stereo = 8 pairs (2 x Cat5)
• TWO way nearly full version of SCART = 11 pairs (3 x CAT5)

The Subwoofer and center channel on 5+1 can be combined and split as the frequency band is separate. Thus it can use 5 pairs rather than 6. You can in reality combine centre & Subwoofer to R and also L and mostly separate them later. Mathematically 5.1 can be carried on 3 channels.

I've also unsolderered IR remote sensor and fed it 30m on CAT5 without balun. It would probably work 500m on Cat5 as it is narrow band 0V / 5V 40KHz DC signalling. Some gadgets have an IR remote dongle on a 3 pin jack. That can simply use 2 pair, one for signal & OV and one with +5V and 0V.

Fit LOTS of Cat5 and Ct100 /PF100

I mostly use it for 100Mbps and 1Gbps LAN (All Cat5 is really CAT5e unless you buy some rubbish old stock.).

If not in conduits or near other cables use Shielded CAT5e and earth at one end. For Network RJ45 there are screened plugs for hub/switch/patch panel end.

Phone works on Cat5e too of course. Regular phone cable is only Cat3

thanks, this is the sort of info I am after, I was thinking of the cat5 option or HDMI, but I think this may prove more expensive.

max run I am looking at is about 20m,

btw anyone know how many connections max you can get out of a single LNB, I am considering the future proof option`and am going to run cableing for 3 sky plus HD boxes

will let know you know how I get on, but it will be a while, just weighing up options at the moment

thanks

Hi Watty,

I have been trying to source 'shielded cat5e' but most of the shop workers are looking at me as if Im crazy.....like they never heard of it.

I tried both malpins and peats today

I was told that all cat5e is now shielded!! Is that true?
If not, any ideas where I can buy shielded cat5e.

Dublin area if possible.

I'm doing something simialar but don't know where to start. I'm renovating an old house and want to have sky running to all rooms(5).

I also want to surround sound my bedroom and sitting room. Have a big box of Cat 6 got already. Need a bit of help on where to start as i am a bit of a noob!
