2.5 Surge Protection Requirements
When an AAU is installed on a pole or the top of a pole, the AAU must meet the surge protection
requirements. Otherwise, surge protection measures must be taken.
A direct lightning strike protection measure must be taken (that is, a lightning rod is installed)
if AAU installation meets the following conditions:
l When the AAU is installed on a pole or the top of a pole, the distance between the top of
the pole and the top of the AAU is less than 30 cm (0.98 ft).
l The AAU is not installed within the protection range of the lightning rod.
When a lightning rod is installed near the AAU installation position, the following conditions
must be met:
l The distance between the lightning rod and the top of the AAU must be greater than 30 cm
(0.98 ft).
l The lightning rod must be properly connected to the onsite ground grid.
l The AAU PGND cable must be routed along the inner side of the pole and is connected to
the ground bar of the onsite ground grid.
l In addition to the above conditions, the lightning rod installation must meet other building
surge protection requirements.
