The TCI Model 803 is a compact Direction Finding (DF) subsystem for Communications Intelligence (COMINT) and Electronic Warfare (EW) applications. The 803 integrates seamlessly with TCI’s Blackbird NextGen COMINT / EW platform to provide a complete signal search, collection, direction finding and geolocation solution.
The 803 continuously scans, detects, DFs, and records DF results in tasked frequency channels on a 4 or 40 MHz instantaneous bandwidth. Bandwidth is tunable over the 20 to 3,000 or 20 to 8,000 MHz frequency ranges. The dual 40/4 MHz wideband DF capability enables the Model 803 to detect and capture weak signals in crowded RF environments using the 4MHz instantaneous bandwidth and detect short duration, frequency-agile and wide-bandwidth signals using the 40 MHz bandwidth.
The 803 is available with any of TCI’s single – band VHF/UHF/ SHF monitor and DF antennas. Antenna options include the Model 641
for high – accuracy DF on vertically polarised signals in fixed and mobile applications, the compact, low – profile Model 645 for mobile and transportable applications from 20 MHz to 3,000 MHz. For higher frequencies, the Model 803 can use the Model 647 antenna, the first antenna to provide high – accuracy DF on vertically polarised signals in fixed and mobile applications from 20 MHz to 8 GHz.
