Bridge
Connectorized
Note: When the connectorized version of 600 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.

12.3 Capabilities of the PTP 600 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 600 Series bridge is fixed to is also capable of withstanding the prevalent wind speeds
and loads.

12.4 Wind Speed Statistics

Installers are recommended to contact the national meteorological office for the country
concerned to identify the likely wind speeds prevalent at the proposed location. This will
enable the installer to estimate the total wind loading on the support structures.
Examples of the sort of statistics that are available are:
