Slide an arm of a pair of angled tweezers under the metal neck of one of the antenna connectors on the charging board and lift straight up to disconnect it.

Repeat the process to disconnect the other coaxial connector.

Hold the metal neck of the antenna connector with a pair of tweezers and align the head over its socket on the board.

Use the flat end of a spudger to press straight down on the connector head—it should snap into place. If you're having trouble, reposition the head and try again. Don't try to force the connector into place, or you risk damaging the charging board.
