HC977 Triple-Band Helical Antenna with L-Band
Calian's antenna features a precision-tuned helix element that provides excellent axial ratios and operates without a ground plane
Calian's lightweight HC977 helical antenna is designed and crafted for precision positioning and covers the GPS/QZSS-L1/L2/L5, GLONASS-G1/G2/G3, Galileo-E1/E5a/E5b, and BeiDou-B1/B2/B2a frequency bands, as well as L-band correction services.
Weighing only 42 g, the HC977 features a precision-tuned helix element that provides excellent axial ratios and operates without the requirement of a ground plane, making it ideal for a wide variety of applications including unmanned aerial vehicles (UAVs).
The HC977 features an industry-leading low-current, low-noise amplifier (LNA) that includes an integrated low-loss pre-filter to protect against harmonic interference from high amplitude interfering signals, such as 700 MHz-band LTE and other near in-band cellular signals.
