Antennas


TCI designs, manufactures, installs and supports a broad family of HF and MF Broadcast antennas, HF Communications antennas, and monitoring antennas designed to capture a wide range of signals from 9 kHz to 3 GHz. We build and optimize every TCI antenna for a specific application, including spectrum monitoring, direction finding, signal interception, radio broadcasting, and radio communications. Our best of class engineering skills, experience, and proprietary software modeling tools allow TCI to create antennas for most applications that can be installed rapidly, maintained easily, and which deliver outstanding performance.


 

RF Distribution


TCI produces a wide variety of computer- controlled RF distribution systems that simultaneously distribute and switch RF signals from multi-element antenna arrays to any combination of multiple communications receivers, spectrum monitoring systems and DF systems. TCI RF distribution systems are modular, non-blocking, and loss-less devices available for MF /HF or VHF/UHF coverage, and are expandable up to 31-input by 320-switched outputs.




Receivers


TCI makes specialized receivers for communications, DF/Monitoring and COMINT/SIGINT applications. Our receivers feature hybrid designs with high dynamic range analog RF front ends and high-resolution digital back ends. With digital control, they're ideal for distributed and remote computer-controlled radio systems in networked communications and monitoring/DF systems. In the LF /MF /HF and VHF /UHF bands, we offer both conventional narrowband and wideband receivers optimized for modem signal modulations and rapid detection, acquisition, and DF of wide band signals. TCI wideband receivers provide IF bandwidths up to 2 MHz at HF and 12 MHz at VHF/UHF with processed measurement resolution bandwidths as narrow as 10 Hz.


 

 

 

 

DSP Processing


TCI systems feature high-speed, 32-bit Digital Signal Processors with proprietary application-specific firmware that delivers high-performance measurement and signal analysis for a wide range of signal types and environments. By digitizing and analyzing the outputs from LF/MF/HF and VHF/UHF receivers, TCI DSP-based spectrum processors deliver fast, comprehensive signal analysis, simultaneously scanning, detecting, measuring and analyzing RF signals at scan rates up to 4 GHz per second. In addition, the same DSP hardware is used to extract signal metrics, classify signal types, make DF fixes and generate statistical data on signal activity.

 

System Software


TCI has expert in-house application software design and development capabilities. This allows us to create highly integrated and optimized application-specific software for embedded and real-time control, data processing, digital signal processing, database structures, graphical user interfaces and network management. Our software engineers also work closely with our hardware and system engineers to integrate operation of the complete system, including equipment control, signal analysis, and database management and network administration.
