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
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.

Yes, there are. MK do them in various types.
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
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
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.

You generally need to order this stuff. Places like WF Electrical
will usually have it for next day. You can usually negotiate a fair
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.
