Coaxial help

I need to have a coax connection in another room in my home and was wondering if there is a wireless coaxial solution that can help me out. I really do not want to run new cable if at all possible. This coax connection will be split for networking and maybe TV. Can anybody help?

For networking, you could rig something up with a couple of 10BaseT/10Base2 media converters and a couple of wireless bridges. That won't carry TV though.
