Ideal for precision positioning and RTK surveying systems, the TW3892 dual band GNSS antenna with L-Band from Tallysman provides excellent circular polarized signal reception, great multi-path and out-of-band signal rejection.
The TW3892 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 (LNA), then band-split for narrow filtering in each band and further amplified prior to recombination at the output.
The TW3892 also includes an LNA pre-filter, providing enhanced protection against high level sub-harmonic signals like LTE and near frequency signals such as WiFi.
The TW3892 performs with excellent axial ratios and a tightly grouped phase center variation.
The TW3892 is housed in a permanent mount industrial grade weather-proof enclosure, available in conical or flat radome styles and in grey or white colours. Two options for pole mounting are available an L-Bracket or a Pipe Mount. A 100mm ground plane is recommended for non-roof-top installations.
