How to connect external antennas
Note
The distance between the antennas of the various WLAN interfaces must be at least 1 m.
Figure 6-8 Position of the ports for external antennas with the housing cover removed
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. First connect the cable for
antenna "B" if you want to use two antennas for an interface. Once the cable for antenna
"A" is connected, it is difficult to reach socket "B".
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".
