Imagine having your satellite receiver, DVR or DVD player in one room, and the ability to watch them in another room, without running wires. Or being able to listen to your computer MP3 collection on a pair of powered speakers in another room? You can do just that with the Leapfrog Wireless Audio/Video Transmitter and Receiver System. It even allows you to use the remote control from the other room, so you can actually change the channels on your satellite receiver without having to walk to the main TV room.The Leapfrog Wireless Audio/Video Transmitter and Receiver System is easy to install, requiring no tools or no complicated (or expensive) cable installation. By transmitting across the 2.4GHz frequency band, it gives you the clearest signal with up to a 150' range. Its signals penetrate walls, doors, ceilings and floors without any interference. Multiple transmission channels allow you to select the best signal possible, as well as eliminate interference with other household products that may also use 2.4GHz technology. The Leapfrog Wireless Audio/Video Transmitter and Receiver System features standard F-connectors and RCA jacks, for connection to any type of TV, new or old. It's like getting a wireless transmission system and a separate RF modulator for the price of one product. Per the manufacturer, the unit only works with its included IR emitter.
