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

The HC871 provides precision dual-frequency positioning, supporting coverage for GPS L1/L2, GLONASS G1/G2, Galileo E1, and BeiDou B1. With a precision-tuned helix element, the lightweight HC871 offers excellent axial ratio, and does not require a ground plane to perform.

As with all Tallysman Helical antennas, the HC871 has an integrated pre-filter to support immunity to high-amplitude signal interference, such as LTE and other cellular signals.
