EIRP Calculator

Calculate Effective Isotropic Radiated Power (EIRP) from transmitter power, antenna gain, and system losses. Supports multiple input units (dBm, dBW, W, mW) and shows results in all common units.

How to Use EIRP Calculator

Enter transmitter power (select unit: dBm, dBW, W, or mW), antenna gain in dBi, and optional cable/connector losses in dB. Click Calculate to see EIRP in multiple units with formula.

Step-by-Step Instructions

  1. Enter transmitter power and select unit
  2. Enter antenna gain in dBi
  3. Enter cable and connector losses
  4. Click Calculate EIRP and view results
