We will be in touch
Afternoon all,
Summary: I want to connect a Cable cable to a TV cable to give me Cable signal upstairs.
So, the house we've moved into has TV cables running to many rooms all from a little signal booster downstairs. Next to this signal booster is where the Cable cable comes into the house. It'd be much more useful if I could have the Cable broadband connection upstairs in the study. There's one of the many TV cables running up to the study.
Are Cable cables and TV cables both the same sort of coax? If so, can I take the Cable broadband cable and link it up to one of the TV cables and then do a similar conversion at the other end?
Ta very much,
jon
P.s. I've been away a while whilst the Internet was being brought to my house. It seems a shame that my first post is so boring. I'll get a "which steel hardtail" thread going soon to make up for it.
I don't think so, I just used a length of Cable coax to extend a TV aerial cable in the GF's house and the signal was terrible. I think TV coax is 75 ohm impedance, and I'm guessing cable coax is 50 ohm. If so, you'd need Baluns to adapt between the two.
yes, you can do this. get yerself down to b&q or maplins or somewhere. either get an adpator that will take the cable screw-on and adapt it to ariel, or unscrew the cable termination and fit an ariel one in it's place. just watch the diameter of any cable you buy, it's less of an issue with the ariel connectors, but the cable ones screw onto the outer sheath directly ( well, while wrapping up a bit of the screen with it as well ).
ariel connectors are more lossy though, so try and minimise the connections using them, and keep an example of the cable connector intact until you've re-terminated one so you can get the lengths right.
Cheers for the responses. I'd left for town by the time you'd replied though.
Anyway, I popped into maplin to find the bits. The lad I asked in there was adamant it would not work - "something to do with different frequencies or summit" - but me being a stubborn git (and thinking "I've got a degree in Electronics, of course it'll work") I bought the bits anyway. As it turns out, I was right. Clearly that degree paid off.
footflaps - I suspected there would be some sort of impedance difference and that would relate to the "different frequencies" comment. Seems to work anyway though. Not sure how well it would work the other way round.
Del - I think at present I'm using 3 connectors, I can reduce that by 1 if I go and swap one of the bits.

ah. the healthy disregard for theory that a bit of learning gives you 🙂
'spend a couple of quid and give it a whirl'. good work.
