We pride ourselves in being part of systems that gathers ELINT information for tactical applications.

Our DF/Monitoring product range is widely used in communications intelligence gathering.

Our solutions for ESM assists in the provision of military intelligence via a range of electromagnetic surveillance and collection devices, giving decision-makers timely insights to use in their electronic protection, electronic attack, or other electronic warfare systems.

We have solutions for ECM applications that are designed to assist in the counter-measure of radar, sonar, and other detection systems.

We have a significant number of antennas that can be used for counter-UAS solutions. The products are designed for use in mobile, base station, and man-portable applications

Typically, these are used to prevent unauthorized communication from functioning, either by preventing communications entirely or by introducing spurious messages into the communications system.

Because of the extremely broad range of frequencies that are used to trigger RCIEDs, an effective wideband antenna system is essential to ensure the best possible protection.

HF radio is also useful for linking remote regions to the outside world while VHF/UHF radio is the perfect tool for field communications between numerous locations.

Ensuring secure communications in military applications is mission-critical. Secure communications protect both classified and unclassified traffic on military communications networks, including voice, video, and data.
