The Federal Communications Commission (FCC) in the USA has advised test labs and TCBs to ensure Part 15 applications include antenna gain information in data sheets and/or test reports. Recent audits confirmed that antenna gain information was missing from applications, and many reports stated “antenna gain information is declared by the manufacturer” without additional supporting information.
All Part 15 applications must show the maximum gain of the antenna for the band of operation and how the antenna gain was derived, using a manufacturer data sheet or a measurement report.
Applications granted after August 25, 2022 without proper antenna information will be dismissed. TCBs may request to put applications in an audit status to update antenna information.
