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.
