TW3710 兼容北斗、伽利略严格任务天线

The TW3710 employs Tallysman’s unique Accutenna™ technology covering the GPS L1, GLONASS G1, Galileo E1, BeiDou B1 and SBAS (WAAS, EGNOS & MSAS) frequency bands (1557 to 1606 MHz). It provides truly circular response over its entire bandwidth thereby producing superior multipath signal rejection resulting in higher accuracy of position and timing. This antenna sets a new price/performance standard in its category.
