Adding the Jolt USB In-Line Amplifier to your indoor HDTV antenna increases the available signal strength, so you can receive a clearer picture and more channels. When using the USB port on your TV, the in-line amplifier will only draw power when the TV is turned on, eliminating power consumption. If you do not have a USB port on the back of your TV, a USB power adapter is included for use with any standard AC wall outlet.
