Lightning protection zones
Lightning protection zones are determined by using the ‘rolling sphere method’
(Figure 2-6). As
sess locations on masts, towers and buildings to determine if the
location is in Zone A or Zone B:
• Zone A: In this zone a direct lightning strike is possible. Do not mount the ODU
and antenna in this zone.
• Zone B: In this zone, direct EMD (lightning) effects are still possible, but
mounting in this zone significantly reduces the possibility of a direct strike.
Mount the ODU and antenna in this zone.
WARNING
Never mount the ODU in Zone A. Mounting in Zone A may put
equipment, structures and life at risk.
