Do you ever find that your TV antenna needs a boost? Look no further! The Jolt is a revolutionary digital antenna in-line amplifier designed to amplify TV signals and filter out any RF signals that can hinder picture quality. The Jolt Amplifier makes picture quality clear and vivid, and can even pull in channels outside your antenna's range, resulting in better performance from your antenna. The Jolt can be powered using the USB port located on the back of your TV. The amplifier will only draw power when the TV is turned on, eliminating power consumption - exactly how an amplifier should work. If you do not have a USB port on the back of your TV, a USB power adapter is included to power the amplifier using any standard wall outlet.
