SECURING THE TECHNOLOGICAL EDGE WITH HF SYSTEMS

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.

COMPREHENSIVE RANGE OF HF COMMUNICATIONS SYSTEMS

HF system solutions that meet the most demanding communications requirements, across short, medium and long-distance coverage areas, and in the harshest environments.

Horizontal and vertical log periodics
Suitable for medium to long-distance applications, RFS’ horizontal log periodic antenna performance is virtually groundindependent, with take-off angles that can be tailored to suit particular requirements. Alternatively, the RFS vertical log periodic antenna series provides ground-dependent vertical beam-widths and is characterized by a low-angle radiation that is essentially constant at all frequencies.

Broadband monopoles
Designed for medium to long-distance omnidirectional operation, these antennas exhibit low angle radiation patterns –an economical solution for general HF communications applications

Tactical antennas
RFS’ wide range of tactical man-pack and transportable antennas are available in standard designs or can be customized to meet specific customer requirements.
