TW3887 双频天线支持GPS L1/L2, GLONASS G1/G2, Galileo E1, BeiDou B1/B2及SBASTW3887 双频天线支持GPS L1/L2, GLONASS G1/G2, Galileo E1, BeiDou B1/B2及SBASTW3887 GPS L1/L2, GLONASS G1/G2, Galileo E1, BeiDou B1/B2, and SBAS 北斗双频天线

The TW3887 employs Tallysman’s unique Accutenna® technology covering the GPS L1/L2, GLONASS G1/G2, Galileo E1, BeiDou B1/B2, and SBAS (WAAS, EGNOS & MSAS) frequency bands. It provides truly circular response over its entire bandwidth thereby producing superior multipath signal rejection. This antenna sets a new price/performance standard in its category.

The TW3887 has a pre-filter which increases the antenna’s immunity to high amplitude signals, such as LTE and other cellular signals. 预滤波消除诸如LTE和其它移动通信信号干扰。
