The Lightning Eliminators and Consultants (LEC) Dissipation Array System (DAS) is designed to prevent lightning strikes to an object or structure under protection.

The Streamer Delaying or Static Dissipator devices and air terminals of the Lightning Master Corporation propose to do the same; however, due to their design, their capacity to do so is severely limited and will default to protecting the structure by intercepting lightning strikes to the structure, on itself in most cases, similar to a lightning rod.
