TW3882 Dual GNSS Antenna北斗双频天线

The TW3882 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 TW3882 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 TW3882 is housed in a through-hole mount, weather-proof enclosure for permanent installations. It is available with either a flat or conical radome in either grey or white. The TW3882 is also available with either a TNC or N-Type connector on the base of the antenna or with a flying lead and a variety of connectors. L-Bracket or Pipe Mount (part numbers 23-0040-0, 23-0065-0 respectively) are available for non-rooftop installation.

The TW3882 is IP67, REACH, and RoHS compliant.

A 100mm ground plane is recommended for non-roof-top installations. 非屋顶安装时建议直径100毫米地基板。
