I have a tv which is in the middle of a room and I want to be able to
wirelessly transmit the RF signal to the TV from an aerial socket
which is attached to an external aerial. The signal is not strong
enough to use an internal aerial connected directly to the TV to be
able to recieve quality digital TV. I don't want to have to add any
more coax wiring and so wanted to be able to transmit the RF signal
from the external aerial to the TV.

The problem is I can't find and way of transmitting this, does anyone
have any ideas.

What you want isn't really possible. Not legally, anyway. You'd be trying to
have your own mini-repeater to retransmit the entire UHF band inside your
living room, or else you'd be trying to cram all that data into another
frequency for wireless retransmission. There isn't enough room. You can't
just "convert" RF into S-video. That can only be done after the incoming RF
signal has been tuned to a specific channel and decoded.

If wiring really is a problem, then using a wireless sender (2.4 GHz) with a
Freeview box seems to be your only option. I suspect that you wouldn't
really like this, however - the transmission path is easily disrupted by
people walking in front of it. Wireless senders also don't play nicely with
WiFi networks (and sometimes microwave ovens!). And the quality will not be
as good as feeding the display with RGB.

Should I just bite the bullet and try to get coax to the centre
of the room?

I think you should.
