Tallysman TW3972XF Benefits From:
Excellent interference mitigation
Excellent multipath rejection
Increased system accuracy
Excellent signal-to-noise ratio
TW3972XF features a precision-tuned, twin circular dual-feed, stacked patch element. The signals from the two orthogonal feeds are combined in a hybrid combiner, amplified in a wideband LNA, then band-split for narrow filtering in each band and further amplified prior to recombination at the output. The antenna also has a strong pre-filter to mitigate inter-modulated signal interference from Ligado, LTE and other cellular bands. The TW3972XF offers an excellent axial ratio and a tightly grouped phase centre variation.
TW3972XF is housed in a through-hole mount, weatherproof enclosure for permanent installations.
Already have a housing? TW3967XF (28 dB) and TW3972EXF (37 dB) are available in unhoused for incorporating into custom product designs.
