To connect an external antenna to the T-Mobile KVD21:
1. Remove the case sides of the KVD21 to access the internal connectors more easily. 2. Locate the internal antenna connectors in the corners. 3. Take the pigtail connector and feed it down into the opening. 4. Wrap the pigtail around and attach it securely to the internal connector. 5. Ensure the pigtail fits properly into the space provided. 6. Connect the other end of the pigtail to your external antenna.
Use minimal force when attaching connectors and align them carefully to avoid damage.
