A mounting assembly (300) for coupling to a circuit board (180) is provided. The mounting assembly can include a radio frequency (RF) connector (330) for receiving an antenna, a flexible cable (340) connected to the RF connector, and an alignment wall (350) supporting the flexible cable and providing a guide channel (343) to flexibly mount the RF connector to a mechanical housing (190). The alignment wall can limit the movement of the RF connector to within a tolerance to alleviate a solder stress on the circuit board.
