TCI’s Model 803C COMINT dual 20/2 MHz Wideband DF and Monitor system continuously scans, detects, DF’s and records signal activity, spectrograms and direction & location reports in tasked frequency channels or the entire VHF/UHF band (HF extensions also available). This detailed analysis is available in real-time, or delayed (post facto) modes. The 803C provides the capability to detect and capture weak signals in crowded RF environments, using the 2 MHz instantaneous bandwidth; as well as the ability to detect short duration, frequency-agile and wide bandwidth signals by using the 20 MHz bandwidth.
Complete systems can be configured with any of the TCI DF antennas, from the standard Model 641, to the extremely compact Model 645, or the new Model 643 – the industry’s only dual-polarization DF antenna.
