TW2405/TW2407高精度GNSS天线

The TW2405/TW2407 employ Tallysman’s unique Accutenna™ technology covering the GPS L1, GLONASS G1, and SBAS (WAAS, EGNOS & MSAS) frequency bands (1574 to 1606 MHz). It provides truly circular response over its entire bandwidth thereby producing superior multipath signal rejection resulting in higher accuracy of position and time.

Tallysman独特的Accutenna™专利技术,覆盖GPS L1, GLONASS G1和SBAS (WAAS, EGNOS & MSAS)频段(1574~1606 MHz)。正真在整个频段提供园极响应、优越的多路径抑制,提供高精度定位与时间。

  • Consistent response in all operating temperatures   所有工作温度范围连续响应

The TW2407 includes a tight pre-filter to protect against saturation by high level sub-harmonics and L-Band signals.

OEM antennas are easily detuned by the local environment. Tallysman offers custom tuning services for optimized integration into OEM end-user modules.

TW2407包括紧预滤波,抗高阶次谐波和L波段信号干扰。OEM天线易于解谐。我们提供定制与调谐服务优化终端用户OEM模块集成。

IMPORTANT: Please consider using the TW2406 or TW2408 in place of the TW2405 or TW2407 respectively. The TW2406/TW2408 is 4 mm wider in diameter which permits the placement of drilled plated holes to provide a more secure means of attaching the antenna to your product. The TW2406/TW2408 is electronically identical to the TW2405/TW2407.

为了牢固安装于您的产品上,我们推荐TW2406/TW2408替代TW2405/TW2407,它们在电气上是一样的,不同的是TW2406/TW2408直径宽了4毫米,可以钻孔安装。
