TW3887 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。
The antenna is supplied with a standard 60mm diameter circular ground plane, with a coaxial cable terminated with your choice of connector (right angle MCX is shown in the drawing). Mounting holes are provided for attachment to larger ground planes. Custom tuning and ground plane options may be available, depending on purchase level commitment.
The TW3887 is REACH and RoHS compliant.
