Tallysman TW3972EXF Benefits From:
Excellent interference mitigation
Excellent multipath rejection
Increased system accuracy
Excellent signal-to-noise ratio
Tallysman XF antennas have been designed to mitigate out of band signals and prevent GNSS antenna saturation. Tallysman’s custom XF filtering mitigates all existing signals and new Ligado and LTE signals, enabling the antennas and attached GNSS receivers to perform optimally.
TW3972EXF features a precision-tuned, twin circular dual-feed, stacked patch element. Signals from the two feeds are combined in a hybrid combiner, amplified in a wide-band LNA, then band-split for narrow filtering in each band and further amplified prior to recombination at the output.
