Without an ARP 958-compliant calibration certificate, a test lab's radiated emissions data can be rejected during a defense or aerospace design review. Searching for "SAE ARP 958 PDF Free": The Reality of Access
Transmission measurements (site attenuation) are taken for each pair at a specific distance over a ground plane or in an anechoic chamber.
This is where comes into play. It is the definitive Aerospace Recommended Practice (ARP) for calibrating antennas used in electromagnetic interference (EMI) testing.
This article will explore what SAE ARP 958 covers, its importance, the methodologies involved, and how to access relevant documentation. What is SAE ARP 958?

SAE ARP958 is a standard published by SAE International (formerly the Society of Automotive Engineers). Its full title is Electromagnetic Interference Measurement Antennas; Standard Calibration Method . It is the definitive Aerospace Recommended Practice (ARP)
At its core, the method outlined by ARP958 uses two antennas: one as a transmitter and one as a receiver. The process measures the "insertion loss" of the signal between them. By comparing the power transmitted to the power received, the (AF)—a key coefficient that translates a voltage measured at the antenna into an actual electric field strength—can be reliably determined.
Used widely in military, aerospace, and commercial electronic testing. Why Antenna Calibration Matters
Accredited test laboratories (ISO/IEC 17025) are audited regularly. Auditors require proof of traceability, which includes verifiable, legally obtained copies of all active reference standards. Using an unauthorized bootleg PDF can jeopardize a laboratory's official accreditation. How to Access SAE ARP 958 Legally
