EIRP (dBm)
Transmit power + gain − feeder loss.
EIRP (W)
10^((EIRP dBm−30)/10).

Assumptions & limits
Assumptions & limits
- Transmitter power, antenna gain, feeder loss. Returns EIRP; local limits external. All coefficients and observations are user supplied; results describe only the stated mathematical model. Quantities are deterministic calculations from supplied observations and assumptions; no external data is fetched. Supported limits: Finite inputs only; numeric fields bounded as labelled. Lists and JSON records are limited to 256 entries unless a stricter tool bound is stated. No automatic design approval, legal conclusion, treatment recommendation or safety certification. Transmit power (dBm): minimum None, maximum 1000000000000.0. Antenna gain (dBi): minimum None, maximum 1000000000000.0. Feeder loss (dB): minimum 0, maximum 1000000000000.0.
