Passive rods
The simplest protection
Passive rods or Franklin rods are the most common and simple lightning rods. These can be used as the only sensor element or be part of passive protection systems, complementing the protection in conductive meshes (Faraday cages).
Franklin rods do not perform any special action during the electrical storm process, the protection of these points is based on the position of the rods, the morphology, material, and the physical reaction that takes place in the electrostatic field.
Types of passive rods
Franklin rods for protection against lightning. It can be used as a sensor element or be part of passive protection systems. Includes a brass adapter piece for Ø 45 mm mast and internal connection with round conductor Ø 8/10 mm (50/70 mm2)
