The patented lightweight HC977E helical antenna is designed and crafted for precision positioning and covers the GPS/QZSS-L1/L2/L5, GLONASSG1/G2/G3, Galileo-E1/E5a/E5b, and BeiDou-B1/B2/B2a frequency bands, as well as L-band correction services.
Key Considerations
Weighing only 8 g, the HC977E 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 HC977E 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.
Calian’s provides an embedded helical antenna mounting ring that traps the outer edge of the circuit board to another circuit board or to any flat surface. To facilitate a successful installation and optimum antenna performance, Calian also provides an Embedded Helical Antenna Installation Guide.
