Which antenna group is a solid-state, high-performance, electrically-scanned TACAN antenna system?

The OE-273/URN is recognized as a solid-state, high-performance, electrically-scanned TACAN (Tactical Air Navigation) antenna system. This type of antenna system is designed to provide accurate and reliable navigation information. The solid-state technology used in the OE-273 allows for enhanced performance characteristics, such as improved signal clarity and reduced maintenance needs compared to older, mechanical systems. The electrically-scanned nature means that it can rapidly and efficiently direct its beam without the need for physical movement, which contributes to its high performance in a tactical environment.

In contrast, the other options represent different types of systems or capabilities that may not align with the specific requirements of a high-performance, electrically-scanned TACAN antenna. Understanding the distinctions between these systems highlights the advanced technology and operational advantages that the OE-273/URN offers in modern military navigation applications.
