Wind Loading


It is important that the  Lightning Interception Mast/Air Terminal has minimum wind deflection and that the mast can withstand both constant and gusting winds.

UK Wind Speed Map​

The following map approximately indicates mean hourly wind speeds and actual velocity. However, it must be noted that wind speeds change with altitude, location and height above ground.

With this in mind, it is important to consider local wind conditions when designing a Lightning Protection System.

Lightning Interception Mast selection must take into account wind loading.

Air Terminals are often installed in exposed places – tops of buildings and open terrain. Therefore they must be capable of withstanding local wind conditions.

In order to calculate wind loading conditions, the following information is required:

  • Location and/or coordinates
  • Average wind speed
  • Gusting wind speed
  • Terrain category

We offer a questionnaire relating to calculating wind loading conditions for our Lightweight Lightning Masts.
