: Frequently used to meet requirements for MIL-STD-461 . 2. Antenna Types Covered

When calibrating an antenna, you cannot easily separate the characteristics of the transmitting antenna from the receiving antenna. To solve this, SAE ARP958 utilizes three unknown antennas (Antenna A, Antenna B, and Antenna C).

The primary technique used to determine the absolute gain and antenna factors without relying on a pre-calibrated reference antenna.

Since standards evolve, this feature includes a dynamic sidebar that automatically parses the PDF to display the revision letter (e.g., Revision A, B, C) and the release date. It warns the user if a newer, superseded version exists (linking to the official SAE store for the latest copyright-protected version), ensuring they are aware of the document’s validity for certification purposes.

Disclaimer: While the feature is designed to assist in finding such documents, users must verify the authenticity of any "free" PDF found online against the official SAE International database to ensure they are using the correct, approved revision for flight-critical applications.

If you are looking for specific technical details on near-field coupling or the math behind antenna factor calculations, I can provide a breakdown of the equations.

SAE ARP 958 is an indispensable document for any facility performing EMC testing, particularly under MIL-STD-461. The 1-meter calibration method outlined ensures that antenna factors are accurately determined. For the most accurate, compliant, and up-to-date procedures, professionals should access the latest document through SAE International.
