Siemens SCALANCE W1780 Configuration Manual page 233

Description
The table has the following columns:
● Connector
Shows the name of the relevant antenna connector.
Note
160 MHz channel bandwidth
● Two antennas are used for operation with 160 MHz
● Based on the table, the setting "Antenna Configuration for Channel Width 160 MHz" is
● Only antenna mode RX/TX is allowed.
Antennas
The following antennas do not support operation with 160 MHz:
● ANT793-8DJ
● ANT793-8DK
● ANT793-8DP
● ANT793-8DL
● ANT793-8DQ
● Antenna Type
Select the type of external antenna connected to the device. If the type of your external
antenna is not available, select the entry "User defined".
If you terminate an antenna connection using a 50 Ω terminating resistor, select the entry
"Not used (Connect 50 Ohm Termination)".
● Antenna Gain
If you select the "User defined" entry for the "Antenna Type", enter the antenna gain
manually in the "dBi" unit.
– Antenna Gain 2.4 GHz [dBi]
– Antenna Gain 5 GHz [dBi]
● Cable Length [m]
Enter the length of the flexible antenna connecting cable in meters between the device and
the external antenna.
● Additional Attenuation [dB]
Here, specify the additional attenuation caused, for example, by an additional splitter.

– Spatial Stream 1: First antenna RxA1 + second antenna RxA4
To ensure that the configuration of both antennas is the same, the settings for the first
antenna are configured and automatically adopted for the second antenna.
