This calculator determines the downtilt angle of an antenna based on the heights of the base and remote antennas and the distance between them. It helps optimize signal coverage and reduce interference between cells.
Formula
Downtilt Angle = atan((Hb – Hr) / Distance)
Formula Explanation
- Hb = Height of base antenna (m)
- Hr = Height of remote antenna (m)
- Distance = Horizontal separation between antennas (m)
- atan = Arctangent function, gives angle in degrees
Example
Input: Hb = 50 m, Hr = 10 m, Distance = 500 m
Result: Downtilt ≈ 4.57°
Who uses it
Helpful for RF and telecom engineers in planning antenna alignment for optimal coverage and reduced overlap.
