5. Attach the lower bracket to the antenna as shown in Figure 124 above.
6. Use a local map, compass, and/or GPS device as needed to determine the direction that
one or more APs require to each cover the 90° sector.
7. Ensure that the nearest and furthest SMs that must register to this AP are within the 3-dB
beam pattern of 60° azimuth by 5° elevation with near-in null fill coverage.
8. Choose the best mounting location for your particular application.
NOTE: Use the embedded spectrum analyzer or a commercial analyzer to evaluate the
frequencies present in various locations. OFDM APs need not be mounted next to each
other. They can be distributed throughout a given site. However, the 90° offset must be
maintained. If you want to co-locate these APs with PMP 100 Series APs of the 5.4-GHz
frequency band range, plan to allow at least 25 MHz of separation between their center
channels.
9. Attach the upper bracket to the pole or tower as shown in Figure 125.
