8 Safety Directions

Suggestion for design of a lightning conductor for a GNSS system:
1.On non-metallic structures
Protection by air terminals is recommended. An air terminal is a pointed
solid or tubular rod of conducting material with proper mounting and con-
nection to a conductor. The position of four air terminals can be uniformly
distributed around the antenna at a distance equal to the height of the air
terminal.
The air terminal diameter should be 12 mm for copper or 15 mm for alumi-
nium. The height of the air terminals should be 25 cm to 50 cm. All air ter-
minals should be connected to the down conductors. The diameter of the
air terminal should be kept to a minimum to reduce GNSS signal shading.
2.On metallic structures
Protection is as described for non-metallic structures, but the air terminals
can be connected directly to the conducting structure without the need for
down conductors.
