Tallysman’s HC977EXF Benefits from:
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
HC977EXF 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.
HC977EXF 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 HC977EXF 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.
Tallysman’s eXtended Filter (XF) antenna technology has been designed to mitigate out of band signals and prevent GNSS antenna saturation.
