Protection requirements for the ODU on a high rise building
Applies to ODU deployments only.
If the antenna or ODU is mounted on a high rise building, with cable entry at roof level
(Figure 45) and the equipment inside (Figure 46), then ensure that the installation meets
the following requirements:
• The antenna and ODU are below the lightning terminals and finials.
• A grounding conductor is installed around the roof perimeter, to form the main roof
perimeter lightning protection ring.
• Air terminals are installed along the length of the main roof perimeter lightning
protection ring typically every 6.1m (20ft).
