How to Use:

Prepare the Antenna:
- Ensure you have the correct type of antenna for your ESP32 CAM board, typically U.FL or IPEX.
Connect the Antenna:
- Locate the U.FL or IPEX connector on your ESP32 CAM board.
- Align the antenna connector with the board connector and gently press it into place until it clicks or feels secure.
Position the Antenna:
- Place the antenna in a location that maximizes signal strength. A higher or less obstructed position usually works best.
- Ensure the antenna is not obstructed by other objects or surfaces that could block the signal.
Check Signal Strength:
- Power on your ESP32 CAM and check the signal strength using the onboard diagnostics or application.
- Adjust the antenna position if necessary to achieve the best signal strength.
Maintain the Antenna:
- Regularly check the connection to ensure the antenna remains properly attached.
- Clean the antenna and its connectors periodically to remove dust or debris.
Troubleshoot Issues:
- If you experience poor signal quality, verify that the antenna is securely connected and properly positioned.
- Consider trying different mounting positions or antennas if signal issues persist.

By following these steps, you can ensure that your ESP32 CAM board benefits from the enhanced range and performance provided by the external antenna. Proper installation and positioning will help you achieve the best results in your wireless communication applications.
