TW3865/TW3867 双频GNSS天线
The TW3865 employs Tallysman’s unique Accutenna™ technology covering the GPS L1/L2, GLONASS G1/G2, Galileo E1, BeiDou B1 and SBAS (WAAS, EGNOS & MSAS) frequency bands. It provides truly circular response over its entire bandwidth thereby producing superior multipath signal rejection. The TW3865 offers excellent axial ratio and a tightly grouped phase center. This antenna sets a new price/performance standard in its category. (Previous model TW3805). TW3867 is with pre-filter.
TW3865支持GPS L1/L2, GLONASS G1/G2, 北斗B1,Galileo E1和SBAS (WAAS, EGNOS & MSAS).
