Capabilities Of The Ptp 500 Series Bridges; Table 5 - Lateral Force - Imperial; Table 6 - Lateral Force - Metric - Motorola PTP 500 Series User Manual

Force (in pounds) = 0.0042 . A . v
Where A is the surface area in square feet and v is the wind speed in miles per hour.
The lateral force produced by a single PTP 500 Series bridge (integrated or connectorized
model) at different wind speeds is shown in Table 5 and Table 6.

NOTE
When the connectorized version of PTP 500 Series bridge is used with external
antennas, the figures from the antenna manufacturer for lateral force should be
included to calculate to total loading on the mounting structure.

4.7.2 Capabilities of the PTP 500 Series Bridges

The structure and mounting brackets of the PTP Series systems are capable of withstanding
wind speeds up to 151mph (242 kph). The installer should ensure that the structure to which
the PTP 500 Series Bridge is fixed to is also capable of withstanding the prevalent wind
speeds and loads.
