Tallysman Single Band GNSS Antenna for Reach M+

Tallysman TW4721 is a compact, wideband Accutenna™ technology GNSS antenna that provides accurate reception for all upper L- band GPS, GLONASS, Beidou, and Galileo signals (L1, G1, B1, B1 BOC, B12, E1) and associated augmentation signals (WAAS, EGNOS and MSAS SBAS). Ideal for high accuracy applications while providing high out of band signal rejection, the TW4721 is the smallest dual feed, high performance antenna available, providing truly circular response over its entire bandwidth thereby producing superior multi-path signal rejection. The TW4721 features a novel 25mm dual-feed wide-band patch element that provides a more linear carrier phase response by virtue of the axial ratio that is greatly improved across the full frequency bandwidth. The 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 prior to recombination at the output. The TW4721 is housed in a com
