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 balanced attenuator calculator helps you determine the resistor (R1) values for a balanced attenuator.
The Q, or quality, factor of a resonant circuit is a measure of the…
A helpful tool for computing the Effective Isotropic Radiated Power (EIRP) of an antenna
This calculator helps you determine the values of the resistors R1 and R2 to be used for a bridged-tee attenuator.
What voltage will you choose to use for each of the station batteries?
This calculator will determine the correct antenna downtilt angle given the heights of the antennas and distance between them.
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.
