Wi-Fi Antennas

• AP-303: Internal antenna models.
  • Two vertically polarized dual-band downtilt omnidirectional antennas for 2×2 MIMO with peak antenna gain of 3.5dBi (2.4GHz) and 6.9dBi (5GHz) per antenna.
  • The antennas are optimized for horizontal ceiling mounted orientation of the AP. The downtilt angle for maximum gain is roughly 30 degrees.
  • Combining the patterns of both antennas per radio, the peak gain of the average (effective) pattern is 2.1dBi in 2.4GHz and 5.7dBi in 5GHz.

Mounting

• The AP ships with a (black) mount clips to attach to a 9/16-inch or 15/16-inch flat T-bar drop-tile ceiling
• Several optional mount kits are available to attach the AP to a variety of surfaces; see the Ordering Information section below for details
