Tallysman HC976 Triple-Band Helical GNSS Antenna with L-Band
The HC976 triple-band GNSS 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)] and L-band correction services.
Description
Overview
Weighing only 42 g, the lightweight and compact HC976 GNSS helical antenna 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.
An embedded version is also available: HC976E.
