WebEffective Isotropic Radiated Power (EIRP) =. dBW =. Watts. NOTE: Some companies present the gain of their antennas in dBi, not dBd, as most do. That makes it look like they have the same (or more) gain as other antennas, but subtract 2.15 dB from the dBi and you have leveled the playing field. WebExample 1: calculate the noise power in a 2000Hz wide receiver at 7MHz with a -1dBi antenna at 1000m distance from the source, if the broadband source has a field strength of 30μV/m in 9000Hz bandwidth at 30m distance from the source (FCC 15.209 limit). Answer: -103dBm (S4 in S-meter terms, and well above expected lowest ambient noise).
