Tallysman TW3872XF Benefits From:
Excellent interference mitigation
Excellent multipath rejection
Increased system accuracy
Excellent signal-to-noise ratio

TW3872XF 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.

Mounting options available for TW3872XF are: L-bracket (PN 23-0040-0) or pipe mount (PN 23-0065-0) in addition to this, Tallysman reccomend a 100mm ground plane.

Already have a housing? TW3867XF (28 dB) is available in unhoused for incorporating into custom product designs.
