Tallysman’s TW3887 Benefits from:
Ideal for L1/L2 RTK surveying systems
Great multipath rejection
Increased system accuracy
Great signal to noise ratio
REACH, and RoHS compliant
TW3887 provides excellent circular polarized signal reception, great multi-path and out of band signal rejection.
Tallysman TW3887 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.
TW3887 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’s TW3887 performs with excellent axial ratios and a tightly grouped phase center variation.
Tallysman offers custom tuning services to optimize the performance of the TW3887 for any OEM installation environment.
