HC990EXF GPS/GNSS Antenna by Tallysman Wireless

The HC990EXF from Tallysman is an Extended-filter Embedded GNSS Helical Antenna. This RHCP antenna provides a peak gain of 3 dBi at full bandwidth and has an axial ratio of less than 0.5 dB at zenith. It utilizes Tallysman’s latest wideband helical element design and features a low current, low-noise amplifier (LNA) with an integrated low loss pre-filter to prevent harmonic interference from high amplitude signals. The LNA provides a gain of 35 dB with a noise figure of 2 dB.

The antenna covers the GPS/QZSS-L1/L2/L5, QZSS-L6, GLONASS-G1/G2/G3, Galileo-E1/E5a/E5b/E6, BeiDou-B1/B2/B2a/B3, and NavIC-L5 frequency bands, including the satellite-based augmentation system (SBAS) – WAAS (North America), EGNOS (Europe), MSAS (Japan), and GAGAN (India). It also supports  L-band correction services.

The HC990EXF requires a DC supply from 2.2 to 16.0 V and draws 36 mA of current. It is available in a compact helical-mount enclosure that measures 60 (Dia.) x 26 (H) mm with flying lead (UFL) connectors. The antenna has been designed to mitigate out-of-band signals and prevent GNSS antenna saturation which makes it ideal for use in autonomous unmanned aerial vehicles (UAVs), GNSS positioning, land survey positioning, mission-critical GNSS timing, network timing & synchronization, sea & land container tracking, fleet management & asset tracking, marine & avionics systems, and law enforcement & public safety.
