 Press Releases

  • The full-band GNSS HC990E embedded helical antenna is designed for precise 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 HC990E embedded helical antenna is designed and built for high-accuracy positioning. It is packaged in a very light and compact form factor, making it ideal for a wide variety of applications, especially lightweight unmanned aerial vehicle (UAV) navigation. The HC990E is 60 mm wide and 25 mm tall, weighing only 12 g. It features a precision-tuned helical element that provides an excellent axial ratio and operates without the requirement of a ground plane. The HC990E also features a low-current, low-noise amplifier (LNA) and pre-filter to prevent harmonic interference from high-amplitude signals, such as 700 MHz band LTE and other nearby in-band cellular signals. The HC990E antenna base has a flying lead with a UFL connector. To facilitate the installation, Tallysman provides an optional embedded helical mounting ring, which traps the outer edge of the antenna circuit board to the host circuit board or any flat surface. Tallysman also supports the installation and integration of embedded helical antennas to enable successful implementation and provide optimal antenna performance. Stop by booth #3058 to see the HC990E and other light weight options for your application.


  • Helical Antenna Line
    High-Precision Helical Antennas: Tallysman's helical antennas provide unprecedented performance in lightweight, compact form factor. The line extends beyond single-band GNSS and Iridium support to also include dual and triple GNSS frequency bands + l-band corrections. Tallysman Helical antennas are designed for applications requiring high performance and versatility with an absolute minimum of weight, such as unmanned aerial vehicles (UAVs)....
