HC971

The Tallysman Helical Antenna Family delivers ultralight performance at centimeter-level accuracy.

The HC971 provides precision triple-frequency positioning, supporting coverage for GPS L1/L2/L5, GLONASS G1/G2/G3, Galileo E1/E5, and BeiDou B1/B2. With a precision-tuned helix element, the lightweight HC971 offers excellent axial ratio, and does not require a ground plane to perform.

As with all Tallysman Helical antennas, the HC971 has an integrated pre-filter to support immunity to high-amplitude signal interference, such as LTE and other cellular signals.

Features

  • Very low Noise Preamp, 2.5dB
  • Axial ratio: <2dB typ
  • LNA Gain 27 dB typ
  • Low current: 12 mA typ
  • ESD circuit protection: 15 KV
  • Invariant performance from: +2.5 to 16VDC

Benefits

  • Lightweight (30g)
  • Ideal for L1/L2 RTK surveying systems
  • Great multipath rejection
  • Increased system accuracy
  • Excellent signal to noise ratio
  • IP67, REACH, and RoHS compliant
