HF Systems

TCI offers a full complement of narrowband and wideband integrated HF systems providing the capability to intercept, locate, record and analyze signals of interest to military and intelligence agencies for COMINT (Communications Intelligence) applications. The TCI HF COMINT/DF (Direction Finding) systems cover the range of 0.1 – 30 MHz and feature multi-channel DF for rapid and accurate results and Single-Station-Location (SSL) capabilities with real-time ionospheric sounding.

  • Wide selection of antennas available to meet all requirements
  • N-channel technology – one receiver channel per antenna element
  • All systems utilize TCI’s Wavefront Analysis DF algorithm
  • TCI wideband systems utilize TCI’s DF First™ technology to produce high-speed simultaneous new-signal detection and direction finding, regardless of modulation type
  • TCI HF systems provide fast and accurate DF in a crowded signal environments, under unstable propagation conditions and with co-channel interference
  • TCI systems address tactical and strategic applications
  • Local and remote operation over a network
