Wi-Fi Antennas
AP-503: Integrated downtilt omni-directional antennas for 2x2 MIMO with peak antenna gain of 1.7dBi in 2.4GHz and 4.8dBi in 5GHz. Built-in 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 each of the antennas of the MIMO radios, the peak gain of the combined, average pattern is 1.5dBi in 2.4GHz and 3.9dBi in 5GHz.
