On ebay, I just got this box that will rebroadcast video to ANY UHF/VHF station, and also on coax. I set up my ATI card to switch displays on a hotkey that i programmed to one of the buttons on my ATI remote. I can then take a little portable TV and go within about 500 feet completely wirelessly. This is great especially in an environment like a dorm room. I ended up putting velcro on all the stalls in our bathroom

. Works like a charm.
