Tallysman, a manufacturer of high-performance GNSS antennas and related products, is offering a new light-weight compact GPS L1/L2 + GLONASS G1/G2 antenna, available either as an OEM (TW1829) antenna or in a housed version (TW8829). The antenna is designed for unmanned aerial vehicle use because of its low aerodynamic profile and very light weight. The TW1829 weighs 37 grams and is 48mm (d) x 12.2mm (h). The TW8829 weighs 52 grams and is 47.3mm (d) x 18.3mm (h). The antennas employ Tallysman’s Accutenna technology, which has proven its ability to provide high-level rejection of multipath signals, a phase linear response and tight phase centre variations (PCV). Additionally, the antenna has pre-filters to prevent the saturation of the front end LNA by strong near frequency and harmonic signals. The antenna is available with a choice of connectors and custom cable lengths. Additionally, Tallysman can custom tune the TW1829 for the customers’ enclosure to ensure optimal performance.
