Tallysman® Introduces the HC976 and HC976E Lightweight Triple-Band, Multi-Constellation Helical Antennas

(Ottawa, Ontario, Canada, June 22, 2020) Tallysman® Wireless Inc. is excited to announce the addition of two new models to its industry-leading line of Helical antennas.

The HC976 housed and HC976E embedded helical antennas are designed and crafted for high accuracy positioning in a very light and compact form factor, making them ideal for many applications including: autonomous vehicle navigation (land, sea and air), hand held land survey devices, automotive positioning, and GNSS timing, to name a few. Both models support GPS/QZSS-L1/L2/L6, GLONASS-G1/G2, Galileo-E1/E6, and BeiDou-B1/B3 frequency bands. Regional augmentation services are also supported: WAAS (North America), EGNOS (Europe), MSAS (Japan), GAGAN (India), and high-precision L-band correction services. The key feature of the HC976 and HC976E is the support of QZSS-L6, Galileo-E6 and BeiDou-B3.


The HC976 is 44 mm wide and 62 mm tall, weighing only 42 g. It features a precision-tuned helical element that provides an excellent axial ratio and operates without the requirement of a ground plane, making it ideal for a wide variety of high precision applications. The HC976 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. All Tallysman’s housed helical antennas are enclosed in a robust military-grade plastic enclosure. The antenna base has an integrated SMA connector, a water-proofing O-ring, and three screw holes to enable secure attachment.

Weighing only 12 g and measuring 39 mm wide and 50 mm tall, the lightweight HC976E embedded antenna supports all the features of the HC976. To facilitate installation of the HC976E, Tallysman provides an optional embedded helical mounting ring, which traps the outer edge of the antenna circuit board to the host circuit board or to any flat surface. Tallysman also provides support for installation and integration of embedded helical antennas to enable successful implementation and to provide optimal antenna performance.
