Overview

The lightweight HC871 helical antenna is designed and crafted for precision positioning and covers the GPS-L1/L2, GLONASS-G1/G2, Galileo-E1, and BeiDou-B1 frequency bands.

Features

  • Very low noise preamp: 2.0 dB typ.
  • Axial ratio: ≤ 0.5 dB at zenith
  • LNA gain: 28 dB typ.
  • Low current: 15 mA typ.
  • ESD circuit protection: 15 kV
  • Invariant performance from 2.2 to 16 VDC
  • IP67, REACH, and RoHS compliant

Benefits

  • Extremely Lightweight (29 g)
  • Ideal for L1/L2 RTK surveying systems
  • Great multipath rejection
  • Increased system accuracy
  • Excellent signal-to-noise ratio

Details

Weighing only 29 g, the lightweight HC871 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 HC871 features an 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 HC871 is protected by a robust, military-grade plastic enclosure with 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 two threaded holes in the base for secure attachment of the unit.
