Tallysman TW3967XF 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.
TW3967XF 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 TW3967XF also has a strong pre-filter to mitigate inter-modulated signal interference from Ligado, LTE and other cellular bands. The TW3967XF offers excellent axial ratio and a tightly grouped phase centre variation.
