Configure Fortinet external antenna parameters for specific FortiAPs

You can install Fortinet external antennas on FAP-432F, FAP-433F, FAP-U432F, and FAP-U433F models. Fortinet external antennas can help optimize coverage and overall wireless performance in various installation settings. On supported FortiAP models, you can configure a new FortiAP profile setting and choose from a list of supported Fortinet external antenna models. This setting allows antenna gains specific to the Fortinet external antenna model and the Wi-Fi band (2.4 GHz or 5 GHz) to be taken into consideration by the FortiGate Wireless controller when setting transmit power for a managed FortiAP device.

To see which external antenna and predefined types correspond to which SKU, refer to the Fortinet Antenna Portfolio Data Sheet.

To configure supported external antenna - CLI

1. Create a FortiAP profile and select a platform that supports external antennas. In set optional-antenna, enter the antenna model.

   config wireless-controller wtp-profile
     edit "FP432F"
       config platform
         set type 432F
       end
       config radio-2
         set optional-antenna FANT-04ABGN-1414-P-N
       end
     next
   end

2. Verify the settings have been applied:

   # diagnose wireless-controller wlac -c wtpprof FP432F | grep antenna
       ..
       opt antenna      : FANT_04ABGN_1414_P_N

3. From the FortiAP CLI, check that antenna configurations have been applied:
