Calculation of lateral force (US)
The magnitude of the lateral force can be estimated from:
Force (in pounds) = 0.0042Av
2
Where: Is:
A surface area in square feet
v wind speed in miles per hour
The lateral force produced by a single PMP 450 unit at different wind speeds is shown in Table 28.

0.71 (AP – 5 GHz, 60 Degree Sector) 19 30 43 58 67
0.89 (AP – 5 GHz, 90 Degree Sector) 24 37 54 73 84

0.94 (AP – 3.5 GHz, 90 Degree Sector) 25 40 57 77 89
0.94 (AP – 3.6 GHz, 90 Degree Sector) 25 40 57 77 89
0.29 (SM) 7.8 12 18 23 27
Capabilities of the PMP 450 Series
The structure and mounting brackets of the AP are capable of withstanding wind speeds up to:
• 190 kph (118 mph) – 5 GHz Sector Antennas
• 216 kph (135 mph) – 2.4 GHz, 3.5 GHz, 3.6 GHz Sector Antennas
Ensure that the structure to which the AP is fixed to is also capable of withstanding the prevalent wind speeds
and loads.
The structure and mounting brackets of the SM are capable of withstanding wind speeds up to 190 kph (118
mph). Ensure that the structure to which the SM is fixed to is also capable of withstanding the prevalent wind
speeds and loads.
