Tallysman TW3967LGXF 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.
TW3967LGXF features a precision-tuned, twin circular dual feed, stacked patch element. Two feeds are combined in a hybrid combiner, amplified in a wideband LNA, after which they are band split for narrow filtering in each band and further amplified prior to recombination at the output.
The TW3967LGXF also has a strong pre-filter to mitigate inter-modulated signal interference from Ligado, LTE and other cellular bands. The TW3967LGXF offers excellent axial ratio and a tightly grouped phase centre variation.
