Benefits of the HC977E Embedded Triple-Band Helical Antenna
Extremely lightweight (12 g)
Ideal for L1 / L2 / L5, E1 / E5a / E5b RTK surveying systems
Great multipath rejection
Increased system accuracy
Excellent signal-to-noise ratio
The HC977E is light weight (Just 12 g) and compact. It features a precision tuned helix element. As a result it provides excellent axial ratios while operating without the need of a ground plane. It is ideal for a variety of uses such as 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.
Tallysman’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, Tallysman also provides an Embedded Helical Antenna Installation Guide.
