    Tallysman Wireless Inc. has added two new models to its line of GNSS helical antennas. Also new are two GNSS signal splitters. New Helical Antennas HC976 triple-band helical antenna with L-band, embedded version. (Photo: Tallysman) The HC976 housed and HC976E embedded helical antennas are designed and crafted for high-accuracy positioning in a light and compact form factor, making them suitable for many applications: autonomous vehicle navigation (land, sea and air) handheld land survey devices automotive positioning GNSS timing Both models support GPS/QZSS-L1/L2/L6, GLONASS-G1/G2, Galileo-E1/E6, and BeiDou-B1/B3 frequency bands. Regional augmentation services supported include: WAAS (North America) EGNOS (Europe) MSAS (Japan) GAGAN (India) 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 millimeters (mm) wide and 62 mm tall, weighing only 42 grams. HC976 triple-band helical antenna with L-band, housed version. (Photo: Tallysman) It features a precision-tuned helical element that provides an excellent axial ratio and operates without the requirement of a ground plane, making it suitable 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 waterproofing O-ring and three screw holes to enable secure attachment. Weighing only 12g and measuring 39mm wide and 50mm 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. New GNSS Splitters Photo: Tallysman Tallysman’s two new Smart Power GNSS signal splitters improve GNSS service reliability. GNSS is a critical component in safety, security, timing, and infrastructure applications, all of which require very high availability. Tallysman provides resilient, fault-tolerant Smart Power GNSS signal splitters that are essential to minimize service interruptions. The design of first-generation GNSS signal splitters suffered from a single point of failure: only one attached receiver powered the splitter and the antenna. If this receiver failed or was unplugged, all attached receivers also failed. Tallysman’s current-generation Smart Power GNSS signal splitters, TW162 (one antenna/two receivers) and TW164 (one antenna/four receivers), offer system redundancy and fail-over capability. Photo: Tallysman First, the splitter accepts power from all attached GNSS receivers; if one receiver fails, the next attached receiver automatically provides power to the splitter and antenna. Second, if the antenna fails and does not draw current, it will provide the receiver powering the splitter with a current draw lower than 1 mA, indicating an antenna fault. The Tallysman TW162 and the TW164 are professional-grade GNSS signal splitters that support the full GNSS spectrum: GPS/QZSS-L1/L2/L5, QZSS-L6, GLONASS-G1/G2/G3, Galileo-E1/E5a/E5b/E6, BeiDou-B1/B2/B2a/B3 and L-band correction service frequency band. The TW162 and TW164 are packaged in a robust, compact, lightweight, and waterproof (IP67) corrosion-protected aluminum housing. They splitters are available with either TNC or type-N connectors. Two gain options are available: standard gain to compensate for signal-splitting loss and 10-dB gain.
