A helpful tool for computing the Effective Isotropic Radiated Power (EIRP) of an antenna
Tools
This calculator helps you determine the values of the resistors R1 and R2 to be used for a bridged-tee attenuator.
Tools
This calculator allows you to solve for any of the six variables in the Friis formula for RF transmission: transmitter power, transmitter gain, receiver power, receiver gain, frequency, or distance.
Tools
A Link Budget puts into account all gains and losses a signal goes through in a system as it is transmitted. The calculator calculates the power of the received signal given amplifier and antenna gains, and medium loss.

Given three of the four input parameters (refractive indices, angles of incidence, and refraction) this tool calculates the missing variable based on Snell's law.
Tools
This calculator will determine the correct antenna downtilt angle given the heights of the antennas and distance between them.
