Upgrading Antennas on the LilyGO T-Deck Plus

Overview

The Lilyo TCK Plus is a great device, but extending its range can make it even more versatile. In this project, I upgraded the device by adding an external SMA antenna. This detailed guide outlines the steps involved in the installation process and evaluates the performance of different antenna options.

Materials Used

Lilyo TCK Plus

Longer Antenna

Shorter Antenna

Small Phillips head screwdriver

Precision tweezers

Exacto knife

Hammer punch

Plastic-safe tape

Steps to Install the External Antenna

Disassemble the Device Begin by turning off the device and removing the screws using a small Phillips head screwdriver. Carefully detach the screen and internal components without damaging the board or connectors.

Identify the Antenna Port Locate the SMA connector for the antenna on the board. Disconnect the existing internal antenna gently with tweezers.

Modify the Case Use an Exacto knife to create an opening for the new antenna connector. Ensure the hole is clean and properly aligned to avoid damaging the case.

Install the External Antenna Insert the SMA connector through the modified hole. Secure it with washers and nuts, ensuring the cable is not twisted or damaged.

Reassemble the Device Carefully reconnect the components and reassemble the device. Test the alignment of the screen, buttons, and internal parts before securing the screws.

Attach the Antenna Connect the external antenna to the SMA port and power on the device to verify functionality.

Results

The installation was successful, and the device powered on without any issues. Both antennas provided increased range, with the larger antenna showing a more significant improvement. A follow-up video will include range tests to compare the performance of both antennas.

Future Plans

I plan to evaluate the range performance of both antennas in various environments. Additionally, I will explore further upgrades, such as mounting a larger antenna for stationary use.

Video Demonstration

A complete video of the installation process is available for reference. It includes detailed steps, tips for avoiding damage, and a demonstration of the final setup.

Conclusion

This project demonstrates how a simple hardware upgrade can enhance the functionality of an existing device. With a bit of care and precision, it’s possible to significantly improve the range and usability of the Lilyo TCK Plus.
