Variables for calculating angle of elevation (and depression)
Where:
Is:
b
angle of elevation
B
vertical difference in elevation
A
horizontal distance between modules
To use metric units to find the angle of elevation, use the following formula:
Where:
Is:
B
expressed in meters
A
expressed in kilometers
To use English standard units to find the angle of elevation, use the following formula:
Where:
Is:
B
expressed in feet
A
expressed in miles
The angle of depression from the higher module is identical to the angle of elevation from the
lower module.

Weatherproof the connector on the coax cables (see section
Attaching and weatherproofing an N
type connector
