Key Tactical & Engineering Features
CTIA Symmetry Precision
Engineered to meet rigorous +/- 0.1 dB symmetry requirements, providing high-level accuracy for OTA chamber reflectivity evaluation and professional ripple tests.
Feed Point Contact Isolation
The specialized sleeve design prevents the feed cable from interfering with the antenna's effectiveness, ensuring a pure toroidal radiation pattern.
Reference Grade Dominance
Serves as a reliable gain reference and low-gain efficiency standard for calibrating high-frequency tactical monitoring systems and electronic protection equipment.
Ultra-Lightweight Design
Weighing only 100g, its professional aesthetic and compact profile allow for easy integration into precision 3D positioning towers and fiber-optic masts.
