L1/L2b GNSS 33dB antenna description Ideal for precision positioning and RTK surveying systems, this antenna provides excellent circular polarized signal reception, great multi-path and out-of-band signal rejection. The Antenna features a precision tuned, circular dual-feed, stacked patch element. The signals from the two orthogonal feeds are combined in a hybrid combiner, amplified in a wide-band Low Noise Amplifier, then band-split for narrow filtering in each band and further amplified prior to recombination at the output. The Antenna offers excellent axial ratio and a tightly grouped phase center variation. The Antenna is housed IP67 in magnet mount industrial grade weather-proof enclosure, available with 5m cable.
