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 will determine the correct antenna downtilt angle given the heights of the antennas and distance between them.
