Just so. Now with regard to antenna calibration ... didn't the NBS long consider the Roberts Dipole calibrated *by construction*? What of the NBS standard collinear mentioned in ARRL handbooks as within a fraction of a decibel of 7 dBd? For that matter, what of a simple loop antenna which -- terminated in high enough resistance (and 50 ohms is usually high enough) -- extracts power from the ambient field almost solely as a function of its area?

Signal sources never require calibration as long as their output is measured with a calibrated device. The representative of the certifying organization appears incompetent in this case, unless some information has been left out.
