Also (and these are easily forgotten) Cable clips to suit.

Hi

In reply to:

Pro+ Installation cable
Slightly thicker than CW1308 but white outer sheath means it won't look ugly if put around a skirting board. It has the advantage of having a thicker grade of copper and shielding to further reduce the potential interference.




To note, from what I understand the screening will make things worse unless it is grounded correctly at both ends, and is overkill for the majority of people.

Regards

Phil

The screening won't make things worse, although not as useful as it would have been if grounded it still makes a difference. Try putting your mobile phone in a baked bean tin and see how well the signal works.

My mobile phone works just fine in a tin.

We are talking different frequencies for a start. The screen without earthing at both ends acts just like an antenna, it picks up radio waves of the AM variety but with nowhere for them to go they are transferred to the wires running in it! For the sort of frequencies ADSL runs at the screen isn't much use unless it is grounded.

When you consider the telephone cable has travelled perhaps thousands of meters being completely unscreened in bog standard bundles of cheap and cheerful telephone cable, just what different will a few meters of correctly terminated screened cable make, not a lot.

Regards

Phil

Ahh, but you cheated - you took the baked beans out first !

Seriously though, you are correct. If the screen isn't grounded, at those sort of frequencies, it can quite easily re-radiate the signal, and therefore be about as much use as a chocolate fireguard.

I would use good quality twisted pair cable. If you are running it where noise pickup could be a problem (i.e. alongside power or alarm cables over more than a couple of meter distance), then I would consider using Cat5 (just use one pair), because it has more twists, but the cable has to be solid copper core, whatever you use.

A far better solution is what I always advise - use a filtered master socket - connect your router directly to the ADSL output on that, and then use Cat5 ethernet to all your computers. All extensions go to the filtered side of the socket, and you won't need any other filters in the house for the phone extensions.

Thanks Zebedee.

The cable won't be alongside any existing cabling of any sort.

Agreed, plugging the router into a filtered master, with a run of Cat5e to the office would be ideal. Just not sure how the missus will like having network cable run all the way over and up teh house to the box bedroom!!!

I think I'll stick with the original plan of a new cable run to a convenient location, whilst removing all the old cable. That sould leave me a cable run which simply goes up and over one door frame, and through the wall.

There is another alternative - use Homeplug or Devolo adaptors to use your mains wiring to carry the network data.
