For decades, high-frequency (HF) systems have provided the communications hotline for defense forces and civilian groups around the world. With communications hops of up to 4,000 kilometers, HF systems continue to be a vital component of large-scale installations, and critical for rapid, ever-shifting deployments.

Voice communications have long been the primary focus. But with digital technologies gaining ground, transmitting tactical data via HF systems is an attractive prospect that raises important questions for the personnel responsible for critical communications networks.

Military and emergency-response groups are faced with the need to upgrade their infrastructure to keep maintenance costs under control and ensure the system is future-proof for migration to digital technology. Radio Frequency Systems’ capabilities are among the most advanced in the world for enhancing existing systems and creating both standard and customized HF and tactical antennas.
