The coax TV cable connected to the back of your TV contains radio signals picked up by your TV aerial. The radio signal is made up of a carrier wave and sound and video components all combined together.
When the TV decodes the aerial signal it filters out the Radio carrier wave and splits the signal into separate sound and video signals which are then sent to the TVs audio and video processing circuitry. This process of separating the signals from its radio wave carrier is called de-modulation and is carried out by the de-modulation circuit in the TV.
A SCART connection bypasses the de-modulation circuit in the TV and feeds separate audio and video signals directly into the audio and video processing circuitry. Bypassing this circuit gives better picture quality as there is less processing done on the signal and the audio and video components can't interfere with one another.
There is no direct way of re-wiring the SCART cable to enable it to be conected to the aerial socket because the signals aren't in the right format.
However, the good news is that you can purchase a magic box called a Modulator which will take the separate audio and video signals from the SCART, combine them with a radio carrier wave and output them via an aerial socket which can then be connected to your TV via a coax cable. You then tune a spare preset on the TV into the modulator and the signal from the SCART can then be viewed by simply chaning channel.
This is very useful for connecting a device like a DVD player which only has SCART output to a TV with no SCART socket.
I think these boxes retail for about 40 or 50 quid.

If your Freeview have 2 Scart sockets on the back, try swamping them round, One would be for TV and the other is for sending the picture to the Video. If the DVD is connected to the Freeview and the Freeview in turn is connected tot he TV, some Freeview machines would pass the signal through to the TV when Off, yet sadly , quite a few would not. If you are using a Scart Hub, it may be the reason too, you can obtain Electronic/Automatic Scart hubs that would pas the signal of the selected device via it's remote control. I found it much easier to make sure that my TV had 2 Scart Socket at least to help me resolve such issues. Another thing to look for, is if your TV has Audio/Video Phono jacks input, they would be marked as Video, Audio left and Audio right, with Red, White and Yellow colours, you can obtain a Scart to Phono cable and that would allow you to use AV1 and AV2 one for each device with no interference from each other. Hope this helps...

The coax cable provides a signal from the aerial suitable for the tuner in the TV or video equipment. Scart provides sound and picture information. To get from coax to scart, you need a tuner and demodulator. To get from scart to coax you need a modulator.
Both of these can be found in a VCR. Since these are now regarded as obsolete, you can pick one up for next to nothing and use it to connect all your equipment together.

No way. Can't be done. Coax is for the Antenna. Scart is for TV to Digi box, or DVD player.

Well it would be possible to connect it to one of the 20 pins on the scart plug, but why on earth would you want to???

You can buy an adaptor from radio shack or Maplins.
