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.
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.
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.
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
