Note: The Antenna ID must be selected in conjunction with the Antenna Control Method to
configure proper use of any of the antenna options.
Note: The RBT-4102-EU has been approved for use with these external antennas. Some
countries restrict or require a license when using outdoor antennas. Please refer to the
conditions of use located in the front of the RoamAbout Wireless RBT-4102 Installation Guide.
Note: In normal mode, the access point provides a channel bandwidth of 20 MHz, and supports the
maximum number of channels permitted by local regulations (e.g., 13 channels for the United
States). In Turbo Mode, the channel bandwidth is increased to 40 MHz to support the increased data
rate. However, this reduces the number of channels supported (e.g., 5 channels for the United
States).
