Note : Make sure that the weep hole is positioned at the lower edge of the antenna
bracket as shown in Figure 4-8.
5. After installing the antenna, use the PHS Signal Analyzer to
check the receiving signal level. Measure the reception

values are as follows :
• RX LVL: more than -78 dBm (35 dBµV)
• Frame Error Rate: less than 2%
