Tallysman HC990EXF Extended-Filter GNSS Helical Antennas

Tallysman HC990EXF Extended-Filter GNSS Helical Antennas are designed for precision positioning and cover GPS/QZSS-L1/L2/L5, GLONASS-G1/G2/G3, GalileoE1/E5a/E5b/E6, and NavIC-L5 frequency bands. HC990EXF antennas utilize the helical element design and provide 67MHz of signal bandwidth, supporting the entire upper GNSS band and L-Band corrections and 136MHz of the lower band signal bandwidth. These antennas feature a high peak gain of 2.5dBi and 0.5dB axial ratio, enabling excellent multipath mitigation and a precise phase center. The precision-tuned helix element enables excellent axial ratios and operates without requiring a ground plane, making the series suitable for a wide variety of applications, including unmanned aerial vehicles (UAVs). Tallysman HC990EXF Extended-Filter GNSS Helical Antennas are designed for precision GNSS positioning, mission-critical GNSS timing, and marine and avionics systems.
