The antenna downtilt and coverage calculator (also known as antenna tilt angle calculator) is used to determine the approximate downward angle, measured in degrees, which the transmitting antenna is to be positioned for optimal signal strength and coverage. This antenna coverage and tilt angle calculator also provides, given a beam width, the inner and outer radii of beam's coverage. 

*Results of this antenna down-tilt coverage calculation are to be used simply as a guide and represent a first order approximation only.

Calculation

Result:

Downtilt Angle:-0.02984 deg
Inner Coverage Radius:Infinity ft
Outer Coverage Radius:611.9 ft

Antenna downtilt coverage calculations are necessary in many common applications requiring the use of directional RF antennas including cellular networks, distributed antennas systems (DAS), antenna base stations, remote antenna sites, land mobile radio (LMR) applications and many others.

**Note: Like our antenna downtilt and coverage calculator, all of our RF calculators allow SI prefix input. For example, if you wish to input "25000000", just type "25M" instead. See the quick-reference table below for all compatible SI prefixes.
