Hi all,

Am currently in the middle of a house build and am running my own data and video cables around the house. Reading though the TCF guide i see they are recommending tri-shield RG6 as a minimum for the runs around the house. Looking around it seems the options for purchasing is really either quad or dual shield.

So, my question is, is it worth the extra cost at this point to put in the quad shield, what would be the most you would expect to pay ?

Having a mosey around you can get the quad at jaycar for ~1.50 a metre (belden, 100M+ price) but it being jaycar i would expect this would be somewhat expensive. The electrician wiring the house for power has given us access to his radcliffes (JA russell) trade account. would you expect these types of places to stock quad and would it be similar prices to what's available on-line ?

Any comments gratefully received.

Thanks

Hi, even though the TCF spec's quad, you will find 99% of RG6 installed in houses is to Sky's current spec which is duo bond (ie dual). If you are in a TCL area (Wellington/ Kapiti/ ChCh) then you should install Tri Shield, although typically the Tri that most suppliers has is non flooded so any cables to the outside/roof should be Duo as these also are unlikely carry TCL traffic.

My wholesaler (Corys'/Mastertrade) dont normally carry Quad, personally I have had no known issues with interference on DVB-T services with DuoBond, in Aus there is a big thing about using Quad to reduce inteference on DVB-T, but those issues normally only apply to VHF which we dont use here. By the time you get to UHF most man made noise has dispated enough to be irrelivent.

my 2c I am sure others will have theirs

I agree as above.

Quad is not needed, although if you run dual and telstra come to install their gear, I have heard of cases where they refuse to use the existing (dual) cable.

I would and do install tri shield only when the customer thinks they might be going to use telstra, otherwise I install dual shield.

In saying that, I have over many years successfully used RG6 Dual shield cabling for lots of telstra applications and have had no problems.

Thanks guys, Dual it is then. I was leaning that way already as live in Dunedin so telstra not an issue and the new house is 15km from the town centre so any kind of cable is not likely to be an issue for some time to come :)
