Vaisala recommends an air terminal for all mast structures that reach 10 meters (33 feet). For mast structures that reach 6 meters (20 feet) or lower, an air terminal is recommended in regions with high lightning density. Especially in tropical or sub-tropical regions, a lightning protection system is a necessity. Install the air terminal so that the tip is as high above the instruments and sensors as possible.
