cctv cable

[KEVINDOE]

Morning all,,

On a job at the moment where the customer can get cctv cable from his mate for nothing,,as there is a sky connection in all four bedrooms ,,
He tells me his mate said cctv cable will be ok for sky aswell....anyone know if this is the case??

Thanks Kev

That doesn't sound like good advice to me, You may get a picture yes, but not meant for sky, I always use something like CT100 for sky, and RG6 for standard freeview UHF signal

RG59 for CCTV, buy some "Shotgun" / "Siamese" cable for CCTV giving you 12v in one run

Don't know of any reason why CCTV coax can't be used for Sky

Try this for coax info

Switched on to Coaxial Cable

Just need to make sure it is 75 ohm coax as 50 ohm will cause problems

 

[KEVINDOE]

The cable concerned is RG59 RoHS -X1132 apparently looks like it is 75ohm stuff

 

[UNG]

Not sure how you tell from the look that it is 75 ohm but RG59 is 75ohm coax

Ahh, got that from a cctv supppliers web site, thanks for the help

As Magic-sid said you will get a picture, but it will not be as good as if it were CT100, PF100, Belden1694 the list goes on.

The picture you have may well be okay.

What problems would it cause

Utter rubbish picture, if it allows one to get through!

Can you explain exactly why ?

 

[Golden_Boy]

If you make statements like the above why cant you explain why?

Have thought of looking it up on Google! Explaining it on here could result in a long post and you will still be asking questions

Some of us are working our butts of today and can't be bothered to fill the whole thread up on the differences of 50 and 75ohm signals and the VSWR, just take our word for it.

Why bother asking for ADVISE then argue about it You have been Advised that the picture wont be good quality and if the client is anything like my pro in law he will expect a perfect picture in every room and YOU will get the blame even tho he supplied the keechy cable

Extract...

"RG59 has a small center conductor, circa 20AWG in American sizing terms, foam (usually) dielectric and single (usually 80 - 90% coverage) braided shield.

RG6 has a bigger diameter core, around 18AWG, a thicker dielectric and usually a 100% coverage foil shield which is then covered by 80 - 90% braided shield. Hence, it will offer a better performance than RG59"

Dont shout at me???,, i just asked the original question ???

 

[Mark_Burgess]

Dont worry Kevindoe, not aimed at you

 

[KEVINDOE]
