It hooks up by USB and a port for your off air antenna. You basically hook up the USB cable, power cord to the AM-21, then a shorty power cord to the receiver, then hook up the off air antenna and you are done except for setting it up in the receiver. Go into the menu, then antenna and scan for the off air channels. They will also show in the guide after it is installed. They are available from many places including DirecTV itself. About $55 to $60. Works very well so far.
