How to fill it
Fill the inputs. The tool shows the outputs.
On the tool screen, Calc is the working sheet. Presets stores values you reuse. Reference is the formula, assumptions, and provenance below.
Formula
ERP = P_TX − losses + G; ERP = EIRP − 2.15 dBInputs
| Name | Unit |
|---|---|
| TX power | dBm |
| Cable loss | dB |
| Connector loss | dB |
| Antenna gain | dBd |
Outputs

| ERP (hero result) | dBm |
Diagnose
This tool does not attach diagnose observations.
Assumptions
- Output is dipole-referenced. Entering dBi still converts correctly.
- Losses are positive magnitudes.
