How to use

Place the antenna in a location with the clearest line of sight possible toward broadcast sources, such as near a window or an elevated shelf. Connect the antenna coaxial cable to the TV’s aerial input, then plug the USB power lead into a USB port on the TV or a USB power adapter to enable the amplifier. Use the TV’s channel scan or auto-tune function to search for available channels. If reception is weak, try small adjustments to the antenna position or try different room locations to find the best signal.

Recommendations

For optimal results, use the USB power supply provided by your TV or a stable 5V USB adapter; avoid powering from unstable or low-current USB hubs. Keep the antenna clear of large metal objects and electronic devices that may cause interference. In areas with marginal reception, try positioning the antenna near a window and rerunning the TV channel scan after each adjustment.
