Weighing only 42 g, the lightweight and compact HC976 GNSS helical antenna from Tallysman 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 HC976 features an industry-leading low current, low-noise amplifier (LNA) that includes an integrated low-loss pre-filter to prevent harmonic interference from highamplitude signals, such as 700 MHz band LTE and other nearby in-band cellular signals.
All Tallysman GNSS helical antenna elements are protected by a robust military-grade IP67-compliant plastic enclosure. The enclosure’s base provides three threaded inserts for secure attachment, as well as a rubber O-ring around the outer edge to seal the antenna base and its integrated SMA connector.
