How to use

Connect the antenna to the aerial input of your television or set-top box using the appropriate coaxial connector. Place the antenna in a location with the least obstruction, such as near a window or elevated on a shelf, and perform an automatic channel scan on your TV or tuner to detect available channels. If reception is weak, try reorienting the antenna or moving it to different positions to find the best signal. No additional power supply or configuration is required for basic operation.

Recommendations

For best results, position the antenna as high as practically possible and avoid placing it behind large metal objects or inside closed cabinets. If you are in an area with very weak reception, consider combining this indoor antenna with an external amplifier or an outdoor antenna solution. Regularly run channel scans after relocation to update the channel list.
