Alaris The RF Technology Group has established itself as a leading provider of tactical and compact DF antenna solutions through continuous innovation in antenna design, RF electronics and system integration. By combining the specialist expertise across the Group, our engineers develop solutions that enable operators to locate RF signals quickly and accurately, even in demanding operational environments.
A major focus in the evolution of DF technology has been the reduction of size, weight and power requirements while simultaneously increasing frequency coverage, bearing accuracy and deployment flexibility. Through advanced antenna architectures, precision element design and optimised calibration techniques, the Alaris Group has developed systems capable of delivering accurate bearings across wide frequency ranges from highly deployable platforms.
Alaris Antennas offers a comprehensive range of tactical DF antennas designed for fixed, mobile and manpack applications. One of the latest additions to the portfolio is the DF-A0389, a compact quad-band DF antenna covering frequencies from 20 MHz to 18 GHz. Designed for tactical operations, it features four-channel correlative DF with integrated low-noise amplification, passive bypass capability, GPS, and onboard navigation in a highly portable solution.
Complementing these capabilities, Alaris Cojot offers specialised compact DF antenna systems for applications where low profile, reduced size and operational mobility are essential. These antennas are particularly suited to vehicle-mounted, covert, dismounted and rapidly deployable missions, providing sophisticated DF performance in exceptionally compact form factors.
Several of these compact DF solutions incorporate Active RF Electronics, developed through collaboration between Alaris Linwave and Alaris Kuhne. The electronically enhanced antennas enable seamless communication between the antenna and receiver system, simplifying integration, supporting system configuration, and enhancing overall operational efficiency.
Together, the DF solutions developed across the Alaris Group demonstrate the Group's commitment to advancing direction-finding technology. Through ongoing investment in innovation and product development, the company continues to deliver advanced solutions that help users achieve superior situational awareness and respond rapidly to RF activity in mission-critical environments.
