Antenna Downtilt and Coverage Calculator

The Antenna Downtilt and Coverage Calculator (aka 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 tilt angle calculator also provides, given a beam width, the inner and outer radii of beam's coverage. 

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

Antenna downtilt 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.

Pasternack carries a large variety of RF directional antennas including in-ceiling dome antennas, Yagi antennas, passive and active GPS antennas, patch and panel antennas. Our directional antennas operate at broad frequencies ranging from 700 MHz to 6.4 GHz and are designed to work within the L1, L2, ISM, GSM, WIMAX, Wi-Fi, UMTS or dual band cellular frequency bands.
