L1/L2/L5/L6/G1/G2/G3/E1/E5a/E5b/E6/ B1/B2/B2a/B3/NavIC-L5/L-band | 35 dB
The HC990E embedded helical antenna is designed for precision positioning, covering 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) available in the region of operation [WAAS (North America), EGNOS (Europe), MSAS (Japan), or GAGAN (India)], as well as L-band correction services.
The patent-pending HC990E utilizes Tallysman’s latest wideband helical element design. The antenna element provides 70 MHz of signal bandwidth supporting the entire upper GNSS band and L-Band corrections (1536 – 1606 MHz) and 136 MHz of the lower band signal bandwidth (1164 – 1300 MHz). Strong full-band antenna element support is only one aspect of a precision GNSS antenna. The other key component is the axial ratio which is a measure of how well the antenna captures the broadcast Right Hand Circular Polarized (RHCP) signal and mitigates the reflected LHCP signals. The Tallysman HC990E has a high peak gain of 3dBi, full bandwidth and the 0.5 dB axial ratio at zenith mitigating multipath, and enables the antenna to provide a precise phase center.
Weighing only 12 g, the light and compact HC990E features a precision-tuned helix element that provides excellent axial ratios and operates without the requirement of a ground plane, making it ideal for a wide variety of applications, including unmanned aerial vehicles (UAVs).
The HC990E features an industry-leading low current, low-noise amplifier (LNA) that includes an integrated low-loss pre-filter to prevent harmonic interference from high-amplitude signals, such as 700 MHz band LTE and other near-band cellular signals.
