Leapfrog's remote control extender converts the infrared signal from a remote control into a long-range RF radio signal, allowing A/V systems to be controlled from virtually anywhere in the home without the need for additional equipment or wiring. Remote control extenders use the 418MHz frequency band to command components through any obstacle, including walls and floors. The product is ready to use in seconds, simply by mounting the sending unit to the remote and plugging in the receiver. Remote control extenders come with all the required equipment, including batteries. Just take it out of the box, set it up, and enjoy your components from wherever you choose. RCA and Dishnetwork extenders are designed specifically for your satellite receivers and the RCA units work with most RCA equipment.
