Canopy 400 Series OFDM AP and SM
Figure 8: Alternate Frequencies, and Antenna Gain on "Configuration => Radio" page
Setting External Antenna Gain
The GUI on modules running DFS includes an "External Antenna Gain" field, as shown in Figure
8. Enter the gain of the antenna in this field, and the module will adjust its DFS sensitivity to radar
signals so as to avoid false positives caused by the additional gain.
IMPORTANT!
If an SM displays an External Antenna Gain field on the "Configuration -
> Radio" page, set the field to 17 dBi.
If the SM displays an External Antenna Gain field on the "Configuration -> Radio" page, set it to
17 dBi, disregarding that the SM's 17 dBi antenna is internal to the unit. The External Antenna
Gain field only appears on an SM if the unit is set to a Region that requires DFS on the SM, such
as "Europe".
