Chapter 2. Installation and Configuration
Finally, you should try diversity mode if you feel that even though your SNR values are high
and the throughput has appropriate results today, this may change in the future. An exam-
ple of this is that you install in the Winter when trees have few or no leaves, but you know
that come Spring the leaves will grow back causing problems. It is best to utilize diversity
mode now in anticipation.
Installation with Antenna Diversity
Here is how you install antenna diversity now that you have determined you need it
• Leave the PW620 mounted in a rectangular fashion such that the antenna bracket
is at 90 degree angles to the antenna.
• Insure that the mounting mast of the PW620 is plumb (at exact vertical).
• Choose either Vertical or Horizontal polarity with diversity using AIM.
• Change the antenna mounting bracket of the PW610’s antenna such that it is at a
45 degree angle to the antenna
• Insure that the mounting mast of the PW610 is plumb.
• When AIM enters the Alignment phase, you will see two signal strengths, horizontal
and vertical. You should maximize their value and insure that both the horizontal
and vertical signal strengths are equal. To perform the alignment of the horizontal
and vertical signal strengths, you should plumb the antenna as appropriate to
make these signals equal. An example of AIM’s Alignment response is shown in
Figure 2-14 on page -20.
