This feature removes the friction of finding reliable technical documentation. For small aerospace startups, students, and independent contractors who cannot afford thousands of dollars in annual subscription fees, it provides the necessary baseline data to design precision photometric test equipment, ensuring safety and compliance without financial barriers.
For detailed technical research, you can often find papers and articles that discuss the implementation of SAE ARP 958 in various testing scenarios. Many of these publications are available for free through academic search engines like Google Scholar. Additionally, for a broader understanding, the SAE committee is responsible for maintaining and updating ARP 958 and other related standards.
Many engineers and students search for terms like to access this document. This comprehensive guide explains what SAE ARP958 is, why it is critical for EMC compliance, how the calibration process works, and the legal realities of acquiring the standard. What is SAE ARP958?
SAE standards are highly precise documents developed by committees of industry experts. Because of the rigorous process required to maintain and update them, SAE International sells these documents to fund their operations. A single copy of SAE ARP958 can cost several hundred dollars. sae arp 958pdf free
Neither MIL-STD-461 nor DO-160 explicitly dictates how to calibrate an antenna; instead, they dictate the testing limits. To ensure the testing data is valid, both standards reference SAE ARP 958 as the mandatory or highly preferred method for validating EMI measurement antennas (such as biconical, log-periodic, and horn antennas).
Aerospace Recommended Practice (ARP) 958 is a critical document published by SAE International. It defines the standard methods for calibrating antennas used in electromagnetic interference (EMI) and electromagnetic compatibility (EMC) testing. For engineers, compliance managers, and technicians working in aerospace, defense, and electronics, understanding this standard is essential for ensuring accurate test results.

Originally published in 1968 to standardize measurements for log-spiral antennas, SAE ARP 958 has evolved across multiple revisions—most notably and the latest ARP958E . It specifies the Three-Antenna Method and Two Identical Antenna Method to determine an antenna’s exact Antenna Factor (AF) within a near-field environment.
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.

, it attempts to resemble reality by using another antenna that represents a distributed source in the calibration method.
, incorporate the "three-antenna method" to improve accuracy when using different antenna types, such as biconical or horn antennas. 3. Evolution of the Standard
