Tallysman HC976 Triple-band Helical Antenna + L-band
The HC976 helical antenna is designed 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.
- Extremely lightweight (42 g)
- Ideal for RTK and PPP surveying systems
- Excellent RH circular polarized signal reception
- Great multipath rejection
- Increased system accuracy
- Excellent signal-to-noise ratio
- Industrial temperature range
- Rugged design, ideal for harsh environments
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 a 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.
An embedded version of this antenna is also available. See the related products tab for more information.
