1 Mount elevation is defined as height above bottom of steel structure to bottom of mount, RAD elevation is defined as center of antenna
above grade level (AGL).
The existing and proposed loads listed in the tables above are compared to the tower’s current design capacity
or previous structural analysis. The tower should be re-evaluated as future loads are added or if actual loads are
found different from those listed in the tables. The subject tower and foundation are adequate to support the
above stated loads in conformance with specified requirements.
