This calculator helps you determine the values of the resistors R1 and R2 to be used for a bridged-tee attenuator.
This calculator will determine the correct antenna downtilt angle given the heights of the antennas and distance between them.
This balanced attenuator calculator helps you determine the resistor (R1) values for a balanced attenuator.
A helpful tool for computing the Effective Isotropic Radiated Power (EIRP) of an antenna
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.
This calculator computes the power received by an antenna using Friis formula
