How to connect external antennas
Figure 4-10
For each WLAN port, there are two R-SMA sockets on a SCALANCE W786 to connect
external antennas. The figure above shows how the R-SMA sockets are assigned to the
WLAN ports. With a SCALANCE W786-1PRO, only the socket pair labeled "1" exists; with a
SCALANCE W786-2PRO the sockets labeled "1" and "2" exist.
Perform the following steps to connect a cable for an external antenna to a SCALANCE
W786:
1. Insert the connector on the antenna cable into the R-SMA socket and tighten the sleeve
nut on the socket (key size SW8), tightening torque 0.6 Nm. If you want to use a port for
two antennas, connect the line for antenna "B" first. After connecting the cable for
antenna "A", the socket for "B" is not easy to reach.
2. Screw a terminating resistor to the unused socket if you use only one antenna on a port.
3. Secure the antenna cable(s) with a strain relief clamp. For more detailed information on
this topic, refer to the section "Connecting the cables".
