Tallysman TW3972E GNSS Antenna
Description
Overview
Tallysman’s impressive TW3972E GNSS antenna features a precision-tuned, twin circular dual feed, stacked patch element. Signals from the two orthogonal feeds are merged in a hybrid combiner, amplified in a wide-band LNA, then band-split for narrow filtering in each band and further amplified prior to output. The TW3972E provides excellent axial ratio and a tightly grouped phase center variation. The antenna also has a capable pre-filter to limit signal interference from LTE and other cellular bands.
