This table contains the following columns:
●
Shows the name of the relevant antenna connection.
●
Select the type of external antenna connected to the device. If the type of your antenna is
not available, select the entry "User defined".
Connectors that are not used must have a 50 Ω terminating resistor fitted. Select the
entry "Not used (connect 50 Ohms Termination)".
Note
50 Ω terminating resistor
Each WLAN interface has three antenna connectors. 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.
●
If you select the "User-defined" entry for the "Antenna Type", enter the antenna gain
manually in the "dB" 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.
●
Enter the length of the flexible antenna connecting cable in meters between the device
and the external antenna.
●
