5.3.1 Grounding and Lightning Protection
Proper grounding is critical to the safety, performance and the life of the equipment installed at
the base station. Refer to Figure 5-9. Arcwave recommends that the installer follow the general
grounding practices employed in cellular and PCS base station sites.
Arcwave recommends the following Lightning Protectors from PolyPhaser Corp.
(www.polyphaser.com
). These PolyPhaser devices are designed to bolt directly to the ground
bus. See diagram in Figure 5-9 for circled reference numbers.
