Take care not to puncture the battery with your tweezers—a punctured battery may leak dangerous chemicals or cause a fire.

Use tweezers to grip the top and bottom of the white antenna's coaxial connector, as close to the connector head as possible.

Lift straight up to disconnect the cable.

Be gentle when disconnecting the cable, as it's very easy to tear the socket from the daughterboard.

To re-attach coaxial connectors like this one, hold the connectors in place and gently press them straight down with your finger or the pointed end of a spudger.
