TW2406/TW2408高精度GNSS天线

The TW2406 is electronically identical to the TW2405 with the same performance characteristics. The TW2406 has a larger PCB than the TW2405 (56mm versus 50mm) with drilled holes to permit more secure mounting

The TW2406/TW2408 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.

TW2406/TW2408与TW2405/TW2407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、牢固安装于您的产品上。

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。
