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.
