Antenna Configurations - Cisco Aironet 1520 Series Getting Started Manual

To reduce potential radio interference to other users, the antenna type and its gain should be
Note
chosen so that the equivalent subtropical radiated power (EIRP) is not more than required for
successful communication.
Table 1 lists the supported external 2.4- and 5-GHz antennas.

1. The compact omnidirectional antennas mount directly on the access point.
2. The compact omnidirectional antennas mount directly on the access point.
3. Use of the 4.9-GHz band requires a license and may be used only by qualified Public Safety operators as defined in
section 90.20 of the FCC rules.

Antenna Configurations

Two antenna configurations are available, based on how the access point is mounted. The cable strand
mounting configuration uses three antennas and the tower mount configuration uses four antennas.
Table 2 identifies the antenna ports used and explains the configurations.
