Begins with amplifier output power ((P_t)). Then subtract feedline losses (cable, connectors)—a common beginner’s mistake is ignoring that 10 meters of cheap coax can eat half the power. Add transmit antenna gain ((G_t)), which focuses energy like a reflector in a flashlight.
FSPL (dB) = 20log10(d) + 20log10(f) + 32.44 Tutorial on Basic Link Budget Analysis.pdf
The received power can be calculated using the following formula: Begins with amplifier output power ((P_t))
Any introductory tutorial will immediately introduce the decibel (dB) as the lingua franca of link analysis. Decibels are used because signal power can span many orders of magnitude; adding and subtracting logarithms is far easier than multiplying and dividing large numbers. The fundamental link budget equation is: Tutorial on Basic Link Budget Analysis.pdf
