CT100, CS100, RG6 - ???

[RzB]

I'm putting in some cable runs from satellite dish to Sky Plus box. I'm doing the cable installation because it's a bit of a tortuous run (30M). Then specialist installer will come along, fit extra LNB and connect up to Sky Plus box (donated by eldest son!) .

The specialist installer has told me to get CT100 or CS100 or RG6 cable, and to make sure it's all copper core and braid etc...

So I went to Rex today to buy myself a 100M reel...

"What you want is this RG6 stuff" ... but it's got an aluminium foil layer...

"Yes , we have CT100 but that's not for satellites, that's just normal TV coax" ...

Unfortunately specialist is now on hols...

Any advice on what to buy please...

Thanks, Roy

Go shop somewhere else ! CT100 or even better WF100. RG6 might well work, but is generally prefered for older analogue signals rather than modern digital signals, and not a good idea over a

30m run!

WF100 has a solid "foam" type insulation inside which resist signal degredation through incorrect impedance caused by kinking and tight turns more hazardous on air spaced cores such as CT100.

WF100 is also more resistant to and water ingress if routed through wet areas like along gutters as seems to be a favoured method of cable runs these days (looking around at local dish installs)

WF100 is also used by telewest for their cable modem connections I believe too.

Saying all that, if you have genuine CT100 than get it. If you have more time, order a roll of WF100 off t'internet.

IMHO from my own recent research.

The guy who told you CT100 is just "normal TV coax" is talking rubbish.

CT100/RG6 is what you need. 30m isn't a particularly long run, so CT100 should be fine.

The RG6 has an aluminium foil and the CT100 has a copper foil. I'm sure there are people who have an opinion as to which is better...

Normal TV Coax does *not* have the foil shield, only the braid.

Pete/Rumble/Alan, Thanks for your help. I think I'll go for the WF100 off the web. Thanks, Roy

Not realy an aluminium foil more like some kind of plastic with a silvery appearance. RG6 is not much more expensive than normal tv coax, CT100 and the ones with copper sheild are much nicer and more expensive, use them!

Cable modem/TV coax has copper shield.

The difference between the 2 is much greater over long runs of cable losing alot more signal with RG6.. It is acceptable for Freeview and would work with satellite signals most of the time but why fit cheap equipment what is not designed for the job and the outer coating soon goes hard and cracks easily.. RG6 is used by installer trying to do the job as cheap as possible because theirs always idiots who hugely undercharge and most companies try and match it...Cheap equipment,cheap cable,cheap price = cheaply done job Buy cheap pay twice...
