Power and safety

How much a station actually radiates and at what distance that is safe: ERP and EIRP, RF exposure distance, and power in decibels.

📄️ERP and EIRP calculator

Online ERP and EIRP calculator: dBi ↔ dBd conversion, losses in cable and connectors, and the effective area of the antenna.

Online RF exposure safe-distance calculator: the Ukrainian DSanPiN limits and ICNIRP, time averaging, and the far-field boundary.

Online power converter — mW to dBm and back, with a reference table of typical levels.
