Tallysman’s TW3870 benefits from:
Ideal for L1/L2 RTK surveying systems
Great multi path rejection
Increased system accuracy
Great signal to noise ratio
IP67, REACH, and RoHS compliant

TW3870 provides excellent circular polarized signal reception, great multi path and out of band signal rejection. As a result TW3870 is ideal for precision positioning and RTK surveying systems.

TW3870 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 TW3870 offers excellent axial ratio and a tightly grouped phase center variation.

TW3870 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.

LNA Pre-filter Available
TW3872 provides these additional benefits with an LNA pre filter.
