This spot should be strategically chosen to optimize the antenna's performance, considering factors such as signal direction and potential obstructions. Once the location is determined, mark the position for the connector.

Using a drill with a bit appropriate for the size of the connector, carefully create a hole at the marked spot on the aluminum sheet. Take care to make the hole precise and clean, ensuring that it accommodates the connector securely. After drilling the hole, insert the threaded portion of the N-Type connector through the opening from the underside of the aluminum sheet, allowing the connector to protrude through the top.

With the connector in place, secure it to the aluminum sheet using the provided locking nut. Tighten the nut to fasten the connector firmly to the sheet, ensuring a stable and reliable connection. Once the connector is securely attached, you can proceed to solder the coaxial cable to the connector, establishing the crucial link between the antenna and your WiFi router.

Carefully strip the insulation from the end of the coaxial cable to expose the inner conductor and the shielding. Connect the inner conductor to the center pin of the N-Type connector, ensuring a solid and secure solder joint. Similarly, attach the shielding of the coaxial cable to the outer portion of the connector, establishing a complete and reliable connection.

After soldering the coaxial cable to the N-Type connector, inspect the joint to ensure that it is well-made and free from any loose connections or exposed wires. A secure and properly soldered connection is essential for the effective transmission of the WiFi signal. Once the connection is verified, you have successfully completed the crucial step of attaching the connector to your DIY WiFi antenna, bringing you one step closer to enhancing your wireless network coverage.
