Details
Ideal for precision positioning and RTK surveying systems, the TW3867 provides excellent circular polarized signal reception, great multi-path and out-of-band signal rejection.
The TW3867 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 TW3867 also includes an LNA pre-filter, providing enhanced protection against high level sub-harmonic signals like LTE and near frequency signals such as WiFi.
Tallysman offers custom tuning services to optimize the performance of the TW3876 for any OEM installation environment.
