The SCALANCE W774/W734 has two antenna connectors of the type R-SMA located on the
top of the device.
Follow the steps below to connect a cable for an external antenna to a SCALANCE

1. Insert the connector on the antenna cable into the R-SMA socket and tighten the sleeve
nut of the plug on the socket (key size SW8, tightening torque 1 Nm). If you only use one
antenna, you need to connect this to the device via antenna connector R1 A1 (position

only using one antenna.
