Tallysman’s TW7872 Benefits from:
Ideal for dual frequency RTK surveying systems
Great multi-path rejection
Increased system accuracy
Great signal to noise ratio
IP67, RoHS and REACH compliant
TW7872 provides excellent circular polarized signal reception, great multi path and out-of-band signal rejection. As a result TW7872 is ideal for precision agriculture, autonomous vehicle tracking and guidance.
TW7872 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 TW7872 also includes an LNA pre filter, providing enhanced protection against high level sub-harmonic signals like LTE and near frequency signals such as WiFi.
TW7872 is housed in an industrial-grade weather-proof enclosure that can be surface mounted via magnet, screws or adhesive material.
TW3872 is a fixed mount version of the TW7872
