Antenna Connectors

The SX-550 WLAN Module has two SMT Ultra-miniature coaxial connectors (U.FL). Table 32 describes the connector types.

For single antenna use, connect to the main antenna connector, as shown in Figure 22 .

For diversity antenna use, connect to both the main and auxiliary connectors.
