Antenna down tilt calculator and coverage tool
1. Antenna Down Tilt Calculator and Coverage Tool:
Used to determine the approximate downward angle, measured in degrees, which the
transmitting antenna is to be positioned for optimal signal strength and coverage. It also
provides, given a beamwidth, the inner and outer radius of beam's coverage.
*Results of this calculation are to be used simply as a guide and represent a first order
approximation only.

RF CALCULATION TOOL �
1. Antenna Down Tilt & Coverage Calculcation
Used to determine the approximate downward angle, measured in degrees, which the
transmitting antenna is to be positioned for optimal signal strength and coverage.
2. Antenna Down-Tilt/Up-Tilt & Azimuth Calculation for specific location
Purpose to increase the coverage signal strength to the specific target location such as complaint
area, building etc,. Horizontal antenna installation vs vertical antenna installation.
3. Link Budget Calculator
Link Budget Calculator determines the received signal strength (in dBm) given a systems
amplifier gains, antenna gains and space loss.
4. Free Space Path Loss (FSPL)
Free Space Path Loss (FSPL) calculations are often used to help predict RF signal strength in an
antenna system. Loss increases with distance, so understanding the FSPL is an essential
parameter for engineers dealing with RF communications systems.
5. EIRP Calculator
EIRP Calculator determines the radiated power given the transmitter power, the cable loss to the
antenna, and the gain of the antenna.
6. VSWR / Return Loss Calculator
SWR / Return Loss Calculator will find VSWR, Return Loss, Mismatch Loss, and the Reflection
Coefficient given any one of the listed input types.
7. Power Density Calculator
Power Density Calculator is designed to give the power density, in Watts per square meter, at a
given distance, output power and antenna gain. Please note that this calculator is only valid for
far-field calculations.
MICROWAVE/PATH PROFILE �
1. Path Profile and Bearing Calculation
In telecommunication, a path profile is a graphic representation of the physical features of a
propagation path in the vertical plane containing both endpoints of the path, showing the surface
of the Earth and including trees, buildings, and other features that may obstruct the radio signal.
Google maps can display the path terrain between two points which could be useful for
Microwave and SOTA amateur radio enthusiasts
LOCATION FINDING TOOLS �
3. 1. Triangulation tool
The tracing and measurement of a series or network of triangles in order to determine the
distances and relative positions of points spread over an area, especially by measuring the
length of one side of each triangle and deducing its angles and the length of the other two sides
by observation from this baseline.
