Hi, it is tri shielded alluminium cable.

currently, hardly any Digital or Sky coax meets this spec.. as it is all dual shielded and lacks the 3rd layer as VM cable is manufactured for them specifically.

the only cable that does meet this spec, in fact exceeds it is

Webro HD100

which is, tri shielded copper cable

available in various lengths here.. this exceeds VM spec

Needs the PPC EX6 NT+ connectors though, which have the serrated nut.. this is the only ones VM use now.

PPC EX6 also works, but its a prior version of the connector NT+ version is an improved version

if i extend the broadband cable from superhub to my PC by about 12metres will that effect my broadband performance

Re: cable spec for broadband
 
It might. It depends what the signal levels to your home currently are. If your alterations push the levels beyond tolerance you will have issues.

i am not yet on cable, only being fitted next week

In that case don't do anything, the installer should put it all where you want it. The only thing you need to be prepared to do in advance is put in any ducting, or lift floorboards, if you want the cable well hidden (as the installers don't have time to do any more than run/tack the cable round skirting).

It will only cause services to fail if services weren't installed properly to begin with.

Signal levels should not be installed as borderline but lots of engineers take advantage of a customers ignorance and lack of knowledge and do a botched install.

I have a 15 meter run on mine and signal loss is only 1-2dBmV if that most of the time the signal loss is not even apparent compared to my other cable runs that are shorter.

But seeming as the optimal range is 10dBmV from -3 to 7 for broadband and 3 to -7 for tv the only way a 2dB loss would cause failure of services is if they was on the bottom end of that range to begin with... Which they shouldn't be! As u will never get a 10 dB loss within a house

Re: cable spec for broadband
 
how would i find what my signal strength is

Chris 23-11-2011 19:27

Re: cable spec for broadband
 
If you don't already have any cable service, you can't. Actually if you don't already have cable you have no signal strength at all.

i meant when it was installed

Ah - there are menus in the modem and IIRC in the TV box that show them. But you have no reason to be worrying about levels if you're getting a fresh install. It should be tested and working properly before the installer leaves your house.

thanks for the info

I also thought it was against terms of contract to fit or extend your own cable.

I may be wrong.
