HC975 Triple Band Helical Antenna with L-Band

Tallysman's HC975 antenna covers GPS/QZSS L1/L2/L5, GLONASS G1/G3, Galileo E1/E5a/E5b, and BeiDou B1/B2/B2a frequency bands

Image of Tallysman's HC975 Triple Band Helical Antenna Tallysman Wireless' HC975 is a lightweight helical antenna covering GPS/QZSS L1/L2/L5, GLONASS G1/G3, Galileo E1/E5a/E5b, and BeiDou B1/B2/B2a frequency bands, as well as SBAS (WAAS/EGNOS/GAGAN/MSAS) and L-band correction services.

Weighing 37 g, the lightweight HC975 features a precision-tuned helix element that provides excellent axial ratios and operates without the requirement of a ground plane. This makes it ideal for a wide variety of applications, including unmanned aerial vehicles (UAVs).

The HC975 features a currently 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.

The HC975 is protected by a robust, military-grade plastic enclosure. It has an integrated SMA connector for screw-on mounting that securely seals the unit with an O-ring, complying with IP67 standards. The enclosure also provides three threaded holes in the base for secure attachment of the unit.

Features
  • Very low noise preamp: 1.6 dB
  • Axial ratio: < = 0.5 dB max.
  • LNA gain: 35 dB typ. or 28 dB typ.
  • Low current: 21 mA typ. or 15 mA typ.
  • ESD circuit protection: 15 kV
  • Invariant performance: +2.2 VDC to 16 VDC

  • Extremely lightweight (37 g)
  • Ideal for L1/L2 RTK surveying systems
  • Great multipath rejection
  • Increased system accuracy
  • Excellent signal-to-noise ratio
  • IP67, REACH, and RoHS compliant
