Power Output Calculator
Enter transmitter power and system parameters. The Power Output Calculator instantly computes EIRP, radiated power, gains/losses in dBm and watts.
About the Power Output Calculator
The Power Output Calculator is a precise, scientifically accurate tool that computes transmitter power output parameters including Effective Isotropic Radiated Power (EIRP), power at antenna, and system gains/losses. This Power Output Calculator implements the standard RF engineering formulas used in telecommunications, broadcasting, and wireless systems. Proudly supported by Agri Care Hub.
Scientific Formulas
Power at antenna: P_ant = P_tx - L_feed
dBm to Watts: P(W) = 10^(P(dBm)/10) / 1000
Watts to dBm: P(dBm) = 10 log₁₀(P(W) × 1000)
Why This Calculator Is Essential
Power output calculations are critical in: • Radio and TV broadcasting • Wireless communication (Wi-Fi, cellular) • Satellite uplinks • Radar systems • Regulatory compliance (FCC, ITU limits) • Link budget analysis EIRP determines coverage and interference; accurate calculation ensures legal operation and optimal performance.
How to Use
- Select transmitter power unit (dBm or Watts).
- Enter transmitter power P_tx.
- Enter feedline/cable loss L_feed in dB.
- Enter antenna gain G in dBi.
- Click “Calculate Power Output”.
When Should You Use This Tool?
- Radio station licensing and compliance
- Wireless network planning
- Satellite ground station design
- Amateur radio (HAM) calculations
- Radar and microwave link budget
- Teaching RF engineering
Scientific Foundation
Transmitter power output and EIRP are defined by international standards (ITU, FCC). The decibel scale provides convenient addition of gains/losses. Full theory at Power Output on Wikipedia and all RF engineering textbooks.
