How does the Delphi XM Signal Repeater work?
The Delphi XM Signal Repeater transmitter converts the Satellite radio signal it receives from an Home Antenna positioned by a southern facing window to a 900 MHz signal capable of penetrating throughout the surrounding environment. Repeater Antennae pick up the 900 MHz signal and converts it back to the satellite radio signal. In essence, it serves as a wireless extension cable.
