Use the point of your spudger to pry and disconnect the white antenna cable.

Pry on only the metal head of the connector. Avoid lifting the cable itself as much as possible.

Free the cable from the clip in the top-right of the daughterboard.

During reassembly, these can be tricky to reconnect. Hold the connector in place over its socket and press down with the flat end of a spudger. The connector should snap into place.

During reassembly, be sure to secure the cable to the clip in the daughterboard.
