Datasheet:Overview
Tallysman’s 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). It 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 antenna is also available in an embedded version as well as with L-Band; the HC871E and HC872/HC872E respectively.
