TCI Model 645-8

20 to 8,500 MHz Compact, High-Performance VHF/UHF DF and Spectrum Monitoring Antenna

The Model 645-8 VHF/UHF Antenna is designed for applications requiring a compact, accurate, multi-element, direction finding (DF) antenna, combined with a sensitive omnidirectional monitoring antenna. The 645-8 allows broadband operation from 20 to 8,500 MHz when used in TCI’s Spectrum Monitoring System (SMS) or COMINT DF. Typical DF accuracy is 2 degrees (RMS), 1 degree in a reflection-free environment. The 645-8 supports calibrated signal amplitude measurements over the full frequency range, and includes built-in self-test (BIST) for automatic testing and verification of the antenna’s operational status.
