TW2705  兼容北斗、伽利略

The TW2705 employs Tallysman’s unique Accutenna™ technology covering the GPS L1,  BeiDou B1, GLONASS G1, Galileo E1, GLONASS G1, and SBAS (WAAS, QZSS, Gagan, EGNOS & MSAS) frequency bands (1557 to 1606 MHz). It provides truly circular response over its entire bandwidth thereby producing superior multipath signal rejection.
