(Ottawa, Ontario, Canada, April 25, 2023) Calian®. is excited to announce the addition of the HC990XF housed full-band helical GNSS antenna to its industry-leading line of antennas.

The housed full-band GNSS HC990XF 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/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 HC990XF base diameter is 64 mm and 37 mm tall, and weighs only 45 grams. Its precision-tuned helical element provides full GNSS band coverage, best-in-class gain, an excellent axial ratio and a tight phase center. The HC990XF helical design does not require a ground plane, making it an ideal antenna for UAV applications.

The HC990XF antenna base has an SMA(male) connector, three screw holes for secure attachment and an O-ring to waterproof the antenna connector. Calian also supports antenna installation and integration to ensure customers achieve excellent antenna performance.

The HC990XF antenna supports 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 to provide clean and pure GNSS signals in a noisy RF world.
