Overview

The HC871 is a lightweight helical antenna covering GPS/QZSS L1/L2, GLONASS G1/G2, Galileo E1, and BeiDou B1 frequency bands, as well as SBAS (WAAS, EGNOS & MSAS).

Features

  • Very low noise preamp, 2 dB
  • Axial ratio: <= 0.5 dB max.
  • LNA gain 28 dB typ.
  • Low current: 12 mA typ.
  • ESD circuit protection: 15 kV
  • Invariant performance from: +2.2 to 16 VDC

Benefits

  • Extremely Lightweight (25 g)
  • Ideal for L1/L2 RTK surveying systems
  • Great multipath rejection
  • Increased system accuracy
  • Excellent signal to noise ratio
  • IP67, REACH, and RoHS compliant

Details

Ideal for a wide variety of applications including Unmanned Aerial Vehicles (UAVs), the lightweight HC871 weighs only 25 g and features a precision-tuned helix element that provides excellent axial ratios and operates without the requirement of a ground plane.

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 three threaded holes in the base for secure attachment of the unit.
