Table 1. Vaisala Lightning Protection Kits for different mast types

Vaisala masts come with a passive air terminal that is made of aluminum. The air terminal is connected to a grounding connector at the base of the mast with a down conductor that runs outside the mast.

Mast type Vaisala Lightning Protection Kit
Pole masts or poles with a diameter of 50 mm (1.97 in) or 60 mm (2.36 in) DKL201

CAUTION 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.
