(Ottawa, Ontario, Canada, September 2, 2025) Calian GNSS Inc. is excited to announce the addition of the HC3990XF housed full-band helical GNSS antenna to its industry-leading line of antennas. A key feature of the HC3990XF design is that it does not require a ground plane, making it an ideal antenna for size-constrained applications.  

Calian’s HC3990XF antenna uses a standard through-hole design which supports TNC, type N and cabled connectors. The HC3990XF base diameter is 66.5 mm and is 34 mm tall and weighs only 105 grams. 

The full-band HC3990XF GNSS helical antenna is designed for precise positioning, supporting GPS/QZSS-L1/L2/L5, QZSS-L6, GLONASS-G1/G2/G3, Galileo-E1/E5a/E5b/E6, BeiDou-B1/B2a/B2b/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 HC3990XF antenna features Calian’s eXtended Filtering (XF) technology. Worldwide the radio frequency spectrum has become congested as many new LTE bands have been activated, and their signals or harmonic frequencies can 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 [Band 32 (1452 – 1496 MHz)] and Japan [Bands 11 and 21 (1476 – 1511 MHz)] have also affected GNSS signals. Calian’s XF technology mitigates all these signals. 

Trust Calian GNSS to provide clean and pure GNSS signals in a noisy RF world.
