Small GNSS/GPS Antenna Description The Small GNSS Antenna, model UC-1574-653R, is a compact Quadrifilar Helix GPS Antenna, intended for reduced size, portable products. It is a lightweight QFHA and its internal design is tolerant to mechanical vibration, making it a better choice than ceramic patches for certain challenging environments. The UC-1574-653R attaches via a bottom SMA Female connector (UC-1574-653RS), or its 9/16"-18 threaded plastic base. An O-ring seals the interface from water. Global Navigation Satellite System compatibility This small GNSS Antenna will support all L-band Global Navigation Satellite Systems: GPS, GLONASS, Galileo, BeiDou and QZSS, covering the range of 1547.42-1603.42 MHz. Variants of this antenna may be requested by special request including other functionality and services, such as GSM, LTE, GMDSS, Argos, etc. Call us with your particular application's need.
