Wi-Fi Antennas

AP-303: Internal antenna models.

Two vertically polarized dual-band downtilt omnidirectional antennas for 2x2 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
