I use my iMac as a media centre. Cables run from it to my LCD TV across the room. It works great except for the cables everywhere.

What I'm looking for is a wireless solution. Something I can plug into my iMac at one end and the TV at the other. I've found a few that are OK but I also need to be able to do the same for the TV antennae. The wall plug is on the other side of the room to the TV. A real pain if I watched TV but the little one likes the Saturday morning cartoons.

Thanks.
