The Cyclone APs must be positioned
• with hardware that the wind and ambient vibrations cannot flex or move.
• where a tower or rooftop is available or can be erected.
• where a grounding system is available.
• with lightning arrestors to transport lightning strikes away from equipment.
• at a proper height:
• higher than the tallest points of objects immediately around them (such as
trees, buildings, and tower legs).
• at least 2 feet (0.6 meters) below the tallest point on the tower, pole, or roof
(for lightning protection).
• away from high-RF energy sites (such as AM or FM stations, high-powered
antennas, and live AM radio towers).
• in line-of-sight paths
• to the SMs and BH.
• that will not be obstructed by trees as they grow or structures that are later
built.
