Sending Coaxial single over Ethernet?

[ukmercenary]

Hello

So I've made a slight mistake on my AV setup when I refurbished my house.
Originally I was going to use Virgin Media so had a cable run from the front of my house under the floor to my Zero Node under the stairs.

However ive now got BT Infinity with a YouView Box.
The problem is that it needs to be attached to a TV Ariel and there is no TV Ariel going into the Zero Node under my stairs.

The mistake we made was to have the TV Ariel cable come down through the wall behind the TV (which is on the opposite wall behind the plasma TV which is also mounted on the wall).

There is an ethernet cable running and HDM cable running from behind the TV to the Zero Node I was thinking perhaps I could send the Coxial single over it to the you view box.

Hmm I appreciate I may not have explained this very well quite had too.

I think the only other alternative is to use existing cable to install a free Stat then install a AV Receiver just to switch between the two. As the Youview box will still work just with the Sky channels.

You can't send a TV aerial signal over twisted-pair data cable.

You might be able to put the youview box near the aerial and run the sound/video/remote control signals from the youview box to the TV over the data cable though.

Well you can,

Can't say I have tried it. But I have used HDMI to cat5/6 convertors for Pro AV work and they work a treat. By the way, how long is your HDMI cable run? Because HDMI doesn't work too well when you start using long cables. Anything more than 15 metres and you will most likely run into problems.

They claim it works for UHF TV aerials, though to be honest I find that surprising because of the frequencies involved. If you choose to buy one, talk to them first and tell them you'll want a refund if it doesn't work! Consider adding an aerial amplifier at the input end.

Well I am surprised, but the CPC page seems to say you just use one of those converters at each end, but the PDF talks about hubs.

If you are talking about single channel modulator output then you may well get away without a balun, as there's plenty of power to overcome signal losses and interference. Multi channel direct from an aerial though is rather more fragile.

Yeah, I have not tried it, but it appears it can work. Thing is it will be a costly experiment. Still just might be easier to try running cable somehow.

DTV goes up to around 850 MHz in UK. They appear to work up to 900 MHz. Should work. As long as the cable run isn't too long and its good quality. But yea might need amp for higher freq channels.

Although the bandwidth of the balun goes up to 900 MHz, the cable itself has significant attenuation at that sort of frequency (depending on length). For example, gigabit Ethernet only needs 250 MHz. Would be interested to know if you can make it work, please let us know!
