Tallysman, manufacturer of economical high-performance GNSS antennas and related products, has introduced a through-hole mount dual-band plus L-band GNSS antenna, the TW3892. The introduction of this antenna is a continuation of Tallysman’s expansion into broader band GNSS antennas. The TW3892 antenna employs Tallysman’s Accutenna technology and is capable of receiving GPS L1/L2, GLONASS G1/G2, BeiDou B1, Galileo E1 plus L-band correction services (1213MHz to 1261MHz + 1525MHz to 1610MHz). TW3892 (other radomes are available). Photo: Tallysman This TW3892 is a precisely tuned antenna with a tight pre-filter to protect against intermodulation and saturation caused by high-level cellular 700 MHz and other signals. The TW3892 antenna provides superior multipath signal rejection, a linear phase response, and a tight phase center variation (PCV) at an economical price point. It provides comparable or superior performance to higher priced dual-band GNSS antennas on the market. The TW3892 is designed for precision agriculture, autonomous vehicles, navigation, real-time kinematic, precise point positioning and other applications where precision matters. The ability of the TW3892 to access L-Band correction services extends its utility to a wider range of applications. The TW3892 is housed in a through-hole mount, weatherproof enclosure for permanent installations. For non-rooftop installations, L bracket or pipe mount (part numbers 23-0040-0, 23-0065-0 respectively) are available. A 100-mm ground plane is recommended for non-rooftop installations.
