The ERP&EIRP Calculator is a specialized tool designed to compute two critical metrics in radio frequency (RF) engineering: Effective Radiated Power (ERP) and Equivalent Isotropically Radiated Power (EIRP). These measurements are essential for evaluating the performance of antennas, transmitters, and communication systems.

Usage Guidance:

• Input Parameters: Users must provide the transmitter power (in watts or dBm), antenna gain (in dBi or dBd), and cable/connector losses (in dB).
• Output Metrics: The calculator generates ERP (which accounts for antenna gain relative to a dipole) and EIRP (which references an isotropic radiator).
• Applications: Ideal for RF engineers, network planners, and regulatory compliance checks for wireless systems.

Example Calculation:

Key Notes:

• ERP is typically lower than EIRP since dipole antennas have less gain than isotropic radiators.
• Regulatory bodies often set limits on EIRP to prevent interference.
• Ensure units are consistent (e.g., convert watts to dBm if necessary).
