TW3972 Pre-Filter Triple-Band GNSS Antennas

Tallysman TW3972 Pre-Filter Triple-Band GNSS Antennas feature Accutenna® technology, increased accuracy, and excellent signal-to-noise ratio. These triple-band GNSS antennas offer L-band correction services coverage and are designed explicitly for precision triple-frequency positioning. TW3972 series antennas offer superior multipath signal rejection and a precision-tuned, twin circular dual-feed, stacked patch element. Signals from the two orthogonal 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 before recombination at the output. Tallysman TW3972 Antennas are housed in a through-hole mount, weather-proof enclosure for permanent installation, and an L-bracket or pipe mount is available for non-rooftop installations.
