Installing the XtremeTV HDTV 110 USB 2.0 TV Tuner couldn't be simpler. Find an open USB 2.0 port and plug in the tuner, or USB extension cable if needed. To watch over-the-air HDTV, connect the HDTV antenna to the tuner. To watch analog over cable, use the coax adapter to connect the cable. To connect any external devices (video camera, VCR, game system) that uses RCA output, the video capture dongle is to be used.
