Tallysman, a manufacturer of high-performance GNSS antennas, has launched a higher gain dual-frequency embedded antenna: the TW3870E. The TW3870E antenna has a typical gain of 35 dB which is required by some GNSS receivers, such as Trimble’s BD9xx family of receivers. The antenna is capable of receiving GPS L1/L2 and GLONASS G1/G2 signals. It employs Tallysman’s Accutenna technology, which can provide low axial ratios, high multi-path signal rejection, low noise, tight PCV and a phase linear response. The TW3870E is 60 mm in diameter and has four drilled plated holes for secure mounting within customers’ products. The antenna can be custom tuned to ensure optimal performance. Custom cable lengths and connectors are also available. The antenna is REACH and ROHS compliant. Visit Tallysman’s booth at INTERGEO 2015, Hall E8, Booth 038 to learn more about the TW3870E and other Tallysman antennas.
