Description
The ARM990XF antenna is available in two form factors one includes a 100 mm integrated ground plane, weighing 140 g, and the other one is 83mm in diameter and weighs 138 grams. Both are 19 mm tall and support the ARINC mini bolt pattern of 2.0″ x 1.66″. Calian’s ARM990XF is one of the smallest and lightest housed triple-band precision Mini ARINC GNSS antennas on the market. It has a very tight average phase center variation of less than 10 mm for all frequencies and overall azimuths and elevation angles. In addition to supporting two form factors both models are available with Low Earth Orbit (LEO) qualified components.
Housed in a weatherproof enclosure, the ARM990XF is available in four versions. Model ARM990XF-1 has an integrated 100mm ground plane, Model ARM990XF-2 is 83 mm in diameter. All models are available with either a female SMA or TNC connector.
The new ARM990XF 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.
