The HC976 helical antenna is designed and crafted for precision positioning, covering the GPS/QZSS-L1/L2, QZSS-L6, GLONASS-G1/G2, Galileo-E1/E6, and BeiDou-B1/B3 frequency bands, including the satellite-based augmentation system (SBAS) available in the region of operation [WAAS (North America), EGNOS (Europe), MSAS (Japan), or GAGAN (India)], as well as L-band correction services.

Weighing only 42 g, the lightweight and compact HC976 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 high-amplitude signals, such as 700 MHz band LTE and other nearby in-band cellular signals.

All Tallysman® helical antenna elements are protected by a robust military-grade IP67-compliant plastic enclosure. The enclosure’s base provides two 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.

Tallysman®’s HC976 has passed a rigorous 30-hour vibration test procedure, consisting of five cycles of 2-hour tests per axis (x, y, z):

  • Cycle 1: 1.05 Grms;
  • Cycle 2: 1.20 Grms;
  • Cycle 3: 1.35 Grms;
  • Cycle 4: 3.67 Grms;
  • Cycle 5: 3.67 Grms.
