5.1.2 Antenna Connector
PH8/PH8-P uses either an ultra-miniature SMT antenna connector from Hirose Ltd: U.FL-R-
SMT, or the Molex 07341201 U.FL antenna connector. Both connectors have identical me-
chanical dimensions (see Figure 5). Minor differences in product specifications are mentioned
in Table 11. The position of the antenna connectors on the PH8/PH8-P board can be seen in
Figure 9.
