Tallysman, a manufacturer of high-performance GNSS antennas and related products, has introduced a magnetic-mount triple-band (plus L-band) GNSS antenna, TW7972, and a dual-band antenna, TW7872. They are designed for precision agriculture, autonomous vehicles, navigation, real-time kinematic (RTK), precise point positioning (PPP), and other applications where precision matters. The ability of the TW7972 to access L-Band correction services extends its utility to a wider range of applications. The introduction of these antennas is a continuation of Tallysman’s expansion into broader band GNSS antennas. These antennas are the first releases in a line of new enclosures that will be used for additional broadband GNSS solutions. Photo: Tallysman The antennas employ Tallysman’s Accutenna technology. The TW7972 is capable of receiving GPS L1/L2/L5, GLONASS G1/G2/G5, BeiDou B1/B2, Galileo E1/E5a+b and L-band correction services (1164 MHz to 1254 MHz + 1525 MHz to 1606 MHz). The TW7872 is capable of receiving GPS L1/L2, GLONASS G1/G2, BeiDou B1 and Galileo E1. The precisely tuned antennas have a tight pre-filter to protect against intermodulation and saturation caused by high-level cellular 700 MHz and other signals. The antennas provide superior multi-path signal rejection, a linear phase response, and a tight phase-center variation (PCV) at a new economical price point, Tallysman said. The antennas provide comparable or superior performance to higher priced triple- and dual-band GNSS antennas on the market. The TW7972 and TW7872 are housed in a magnetic-mount, IP67 weather-proof enclosure with pre-tapped screw holes. The antennas can also be ordered without the magnet. The TW3967 (28-dB gain) and the TW3972E (35-dB gain) are the embedded versions of the TW7972. The TW3867 and TW3872E are the embedded versions of the TW7872. They are available with a wide selection of connectors and custom cable lengths, and can be custom tuned by Tallysman to ensure optimum performance within the customer’s enclosure.
