Hi

I have seen mention on here on digital coaxial cable. I understand that is required for HD Freeview Channels 1,2 and 3 and 5:1 sound?

Just bout to do some wiriing to split a Freeview (UHF) signal to another TV.... so about to get some coax cable. Bit is there a specific sort that I should be gettingor is at all digital?
Rapallo have coaxial cable - but its dscribed as being "high quality entry level sub woofer cable'.. which doesn't sound like what I should be to extend my aerial cable.

So my queries really are

1/ what is the ideal cable that I should be using to extend my aerial cable

2/ if there is a difference and digital coax is better then is there a way that I can tell what is currently coming down from the UHF aerial on the roof

- thanks

Zeon

You want RG6 cable I believe. The cable isn't digital as such, it just has different ratings for things like impedance. I would recommend using th screw connectors too. The push in ones are quite unreliable.

SPDIF has a very robust physical layer1 construction that you dont need to worry about the cable used in typical installations. Its designed around a 75ohm coaxial line however in the normal domestic situations of cables of only a few meters in length just basic cheap RCA fly leads are fine.

Subwoofer cable is audio cable. You want rf cable. No such thing as digital or analogue co-ax.
This is what I used

I think you may have got a little confused there. I think the Digital Coax Cable you speak of above is for Audio - Most Set top boxes and AV receivers will have Optical Audio Out (a Toslink plug with a fibre optic cable) or a Digital Coax Output (standard RCA cable works fine here), or both, for moving Audio from the STB to the receiver. It is not needed if you are using HDMI from your STB to a receiver, or if you do not have a receiver in the mix.

If you are splitting your UHF signal to put in another Freeview box (wither STB or TV), you just need RG6 cable as mentioned above, good terminations (F-Connectors) and a good splitter.
