Digital TV aerial lead via modular CAT5 socket?

This weekend I hope to be fitting an aerial cable to feed the digital TV card which Santa brought me. As I have a spare slot in the modular CAT5 box buried in the wall behind the PC, I was wondering whether it was possible to use that in some way, rather than digging a new hole in the wall for yet another cable connection? Are there modular coax modules available?
Presumably you can't wire up coax cable to an RJ45 socket or something?! I know it wouldn't work with an analogue system; but this is my first foray into digital and I don't know whether interference issues etc are worse or better than analogue.
Thx David

Yes, there are. MK do them in various types.
www.mkelectric.co.uk
K5851WHI for a basic coax socket 1 Euro module width K5855WHI for an F type connector (satellite)
K5852WHI for TV and FM diplexer 2 Euro modules width K5853WHI for TF/FM/Sat triplexer
If you need them, they also do BT type phone sockets in the same format.
1 Euro module is 25mm wide 50mm high. Hopefully this is the type of CAT5 modules that you have. There are several vendors doing RJ45 Euro modules.
You should use CT100 satellite grade coax cable for the application. CAT 5 wiring and RJ45 sockets are not designed for this. The actual signals use for digital TV are still delivered using analogue RF transmission and are at a lower signal level than existing transmissions. They are also sensitive to errrors that would likely be caused by reflections resulting from the wrong types of connector and cable being used.

Brilliant! thanks, Andy.

OK. Yes I've already got the correct coax grade.

You generally need to order this stuff. Places like WF Electrical will usually have it for next day. You can usually negotiate a fair discount.......
FWIW, there are also BT phone sockets in the same format and numerous other modular inserts. If you call MK's technical help line, they'll send you a catalogue, although the web site isn't bad.
