Tallysman Wireless Inc. is excited to announce the dual-band low-profile HC871SXF to its industry-leading line of helical GNSS antennas.
The dual-band GNSS HC871SXF helical antenna is designed for precise positioning, covering the GPS/QZSS-L1/L2, GLONASS-G1/G2, Galileo-E1, and BeiDou-B1 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).
The HC871SXF has a precision-tuned, high-accuracy helical element that provides an excellent axial ratio and operates without a ground plane. These features make the HC871SXF ideal for lightweight, unmanned aerial vehicle (UAV) navigation and a wide variety of precision applications.
The HC871SXF low-profile helical antenna is approximately 10 mm shorter than the HC871, but provides the same performance.
It is packaged in a very light (23 g) and compact form factor (34 mm wide by 54 mm high). The antenna base has a male SMA connector. To facilitate installation, the base also has two threaded inserts and an O-ring to waterproof the SMA connection. Tallysman provides support for installation, integration, and optimisation to ensure optimal antenna performance.
The HC871SXF antenna supports Tallysman’s eXtended Filtering (XF) technology. The radio frequency spectrum has become congested worldwide as many new LTE bands have been activated, with their signals or harmonic frequencies being able to affect GNSS antennas and receivers. In North America, the planned Ligado service, which will broadcast in the frequency range of 1526 to 1536 MHz, can affect GNSS signals. Similarly, new LTE signals in Europe (1452 to 1496 MHz) and Japan (1476 to 1511 MHz) can also affect GNSS signals. Tallysman’s XF technology mitigates all these signals.
