Traditional lightning rods act as a target, attracting the lightning strike and channelling it safely to the ground. However, the exact point of impact can be unpredictable, potentially causing damage.

ESE air terminals take a more proactive approach. They emit a continuous upward leader, essentially an electrical streamer, that anticipates the downward leader. This “early streamer” intercepts the lightning strike at a higher point, guiding it safely to the ground through a controlled path.
