Tallysman HC990EXF Embedded Full GNSS Helical Antenna with Extended Filtering+ L-Band (Formerly the HC990E)
The HC990EXF from Tallysman embedded helical antenna with extended filtering 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 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 HC990EXF utilizes Tallysman’s proprietary 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). 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 HC990EXF 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 12 g, the light and compact HC990EXF features a precision-tuned helix element that provide ideal axial ratios and operates without the requirement of a ground plane, making it suitable for a wide variety of applications, including UAVS.
