In the case of biconical antennas, to get the FSAF using ANSI C63.
In the present edition, the most notable addition was that specified biconical antenna calibration data should be reported as NFSAF and corrected to FSAF to be used for product testing and Normalized Site Attenuation (NSA) measurements.
Antenna factors obtained for biconical antennas are NFSAF; the standard requires they be corrected to FSAF using the correction factors provided in Table G.
3, which lists the GSCF, is used together with the FSAF in performing normalized site attenuation measurements (30 MHz to 200 MHz).
Although this is not new, very few people are aware of this FSAF measurement option.
