The bridge’s primary antenna is it’s built-in internal antenna. For some
applications when deploying an WL-575 unit for a bridge link or access point
operation, you may need to mount external antennas and connect them to the
bridge. Typically, a bridge link requires a 5.0 GHz antenna, and access point
operation a 2.4 GHz antenna. WL-575 units acting as managed APs also require
an external antenna for 2.4 GHz operation.

Perform these steps:
1
Mount the external antenna to the same supporting structure as the bridge,
within 3 m (10 ft) distance, using the bracket supplied in the antenna
package.
