Belkin just released it. For your application you would have to buy their "flagship" one which retails for one thousands dollars.
So this is my problem, i just moved in to a condo and i was snooping around the rooms and i realized that i don't have cable jacks in any of my rooms. I found this out when i just ordered Comast cable for the family room. So i was wondering if there is such a thing that if i got a splitter and took the cable from the wall and wireless send it to the other room. i only need it in one other room witch is me and my wifes room. i asked Comcast if they would run a new jack for me but they said sens i live in a condo they will not run any thing for me because if electric lines and what ever they come up with. so just to recap i just need to run coax from the wall (no box) to a wireless transmitter and send it to an other room that does not have a wall jack so then i can watch cable in that room. well thanks!
