Any wireless device with tv out?

i want to know is there any device available here in karachi with a coaxil input and it can transmit the cable signal in the entire home in a wireless way. and each tv / plasma will have the small antenna (2 inches or so) tht could attach with the RF input and receive the signals from tht transmitter so we could see the cable transmission in a wireless way , no hassle of wires to all the tv at home.
