Lightning Protection Zones - Motorola PTP 300Series Deployment Manual

Lightning Protection Zones

When the ODU is installed on a mast, tower or wall, it may be in one of two possible lightning
protection zones:
• Zone A: In this zone a direct lighting strike is possible. Do not mount the ODU 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 in this zone.
