LightPointe calculates the AireLink™ 60 availability vs. distance charts based on internal system
parameters and ITU-R Recommendation P.838-3. These charts are shown below for North American

and 60 cm antenna options. Other rain zone charts as well as a system fade margin calculator for the
AireLink™ 60 products are available upon request. Please contact LightPointe Customer Support for
