Calculation of lateral force (US)
The magnitude of the lateral force can be estimated from:
Force (in pounds) = 0.0042Av

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.
