The AM1 Agile RF Modulator covers all VHF and UHF frequencies.  It features digital channel display, adjustable output and audio levels and F connector inputs/outputs.  Should there be a power outage, your AM1 will power back up on the same channel that you set it to. 

Works great to broadcast the output of your satellite receiver to other TV's in the house or to view your security camera's output to all your TV's on any unused channel.
