Configuration of external antennas
On this page, you configure the settings for the connected external antennas.
Note
50
Ω terminating resistor
Each WLAN interface has three antenna connectors. Connectors that are not used must
have a 50 Ω terminating resistor fitted.
The antennas R1A1 and R2A1 must be always be connected as soon as the associated
WLAN interface is turned on. If no antenna is connected, the relevant interface must also be
disabled for Rx and Tx. Otherwise, there may be transmission disruptions.
Description
The table has the following columns:
●
Connector
Shows the name of the relevant antenna connection.
●
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 Ohms 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]
Here, enter the antenna gain the antenna has in the 2.4 GHz frequency band.
–
Antenna Gain 5 GHz [dBi]
Here, enter the antenna gain the antenna has in the 5 GHz frequency band.
