7. On the receive side of the link, the screen displays a table showing
the packet number received, the frequency at which each packet
was transmitted, the Received Signal Strength Indicator (RSSI) for
each antenna and the antenna that was selected for reception (refer
to Figure 3.6). Use only the RSSI reading from the selected
antenna.

9. Re-align the antennas until the maximum received signal strength
is attained. As you align the antennas, you will see that the RSSI
(received signal strength indicator) continually increases until it
