FortiWLC – Configure Gain for External Antennas

Configure Gain for External Antennas

The total power that an AP produces must not exceed 30dbi; this number includes any antenna gain. Therefore, if an antenna produces 2dbi, the radio can produce 28dbi. FortiWLC

(SD) automatically sets antenna gain; in the case of an AP400, it assumes an antenna with 5dbi and therefore sets the AP400 to 25dbi. This may or may not be correct for your antenna.

To check and change antenna gain, follow these steps from FortiWLC (SD):

  1. Click Configuration > APs (under Devices).
  2. Select an AP ID.
  3. Click the Antenna Property tab.
  4. Select an Interface (1/2).
  5. Change the gain if needed.
  6. Click OK.
