Tallysman’s TW3872 benefits from:
Ideal for L1/L2 RTK surveying systems
Great multi-path rejection
Increased system accuracy
Great signal to noise ratio
REACH and RoHS compliant
TW3872E provides excellent circular polarized signal reception, great multi path and out of band signal rejection. As a result TW3872E is ideal for precision positioning and RTK surveying systems.
TW3872E 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.
Tallysman‘s TW3872E also includes an LNA pre-filter, providing enhanced protection against high level sub-harmonic signals like LTE and near frequency signals such as WiFi.
Custom tuning services are available.
