Installing the Access Point
dipole antennas is a dual-band antenna, covering both the 2.4 - 2.483 GHz band and the 5.25-5.85 GHz
bands. The antenna have a peak gain of about 3 dBi at 2.4 GHz and 5 dBi at 5 GHz. The antenna unit is
gray weatherproof radome for outdoor operations.
External Antenna Mounting Configurations
The selection of the antenna is determined in the configuration of the product. The 1572E antennas can
be mounted on a wall, pole and/or tower mounted. Please refer to the Ordering Guide for a list of
