HC977EXF Embedded Triple-Band GNSS Helical Antenna

Precision Embedded Antenna for Harsh Environments

Calian HC977EXF Embedded Triple-Band GNSS Helical Antenna is designed for precision GNSS positioning across GPS, GLONASS, Galileo, BeiDou, NavIC, and L-Band correction services. With Tallysman’s eXtended Filter (XF) technology, it mitigates out-of-band interference for optimal performance. Weighing just 8 grams, this compact antenna is ideal for UAVs and other critical applications, ensuring reliable performance in congested RF environments.
