GNSS Antenna Kits Specifications
This wide-band antenna is a precision high gain GNSS antenna covering the
BeiDou B1, Galileo E1, GPS L1, GLONASS L1, and SBAS (WAAS, EGNOS,
QZSS, and MSAS) frequency band (1557 MHz to 1606 MHz). It provides very
circular polarized signal reception through the entire bandwidth of the antenna,
thereby providing superior multipath signal rejection. The antenna has a three stage
low noise amplifier, comprised of one input LNA per feed, a mid section SAW to filter
the combined output, and a final output gain stage. An additional pre-filter provides
extra strong protection from near frequency and strong harmonic signals. An
L-bracket for pole mounting and 3-foot BNC(m) to N(f) cable is also included.
