## HC872XF 

## Multi-Constellation Dual-Band Antenna 

**Frequency Coverage:** GPS L1, L2 | GALILEO E1 | BEIDOU B1 | GLONASS G1, G2 + L-Band 

The patented HC872XF helical antenna is designed for precision 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)], as well as and L-Band correction services. 

Calian's eXtended Filter (XF) antenna technology has been designed to mitigate outof-band signals and prevent GNSS antenna saturation. The radio frequency spectrum has become more congested as new LTE bands are activated and their signals or harmonic frequencies [e.g. 800MHz x 2 = 1600MHz (GLONASS-G1)] can affect GNSS antennas and receivers. In North America, planned Ligado signals at 1525 - 1536 MHz can especially impact GNSS antennas that support space-based L-band correction services (1539 - 1559 MHz). New LTE signals in Europe [Band 32 (1452 - 1496 MHz)] and Japan [Bands 11 and 21 (1476 – 1511 MHz)] have also been observed to interfere with GNSS signals. In addition, Inmarsat satellite communication (uplink: 1626.5 - 1660.5 MHz) can also affect GNSS signals. Calian's custom XF filtering mitigates all existing signals and new Ligado and LTE signals, enabling the antennas and attached GNSS receivers to perform optimally. 

Weighing only 42 g, the light and compact HC872XF features a precision-tuned helix element that provides excellent axial ratios and operates without the requirement of a ground plane, making it ideal for a variety of applications, including uncrewed aerial vehicles (UAVs). 

All Tallysman housed helical antenna elements are protected by a robust militarygrade IP69K-compliant plastic enclosure. The enclosure’s base provides two threaded inserts for secure attachment, as well as a rubber O-ring around the outer edge to seal the antenna base and its integrated male SMA connector. 

Calian's helical family has passed a rigorous 30-hour vibration test procedure, consisting of five cycles of 2-hour tests per axis (x, y, z): 

• Cycle 1: 1.05 Grms; 

- Cycle 2: 1.20 Grms; 

- Cycle 3: 1.35 Grms; 

- Cycle 4: 3.67 Grms; 

- Cycle 5: 3.67 Grms.
