The TW1421 employs 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 positional and timing accuracy.

The TW1421 has a tight phase centre variation and truly is the highest performing compact OEM GPS + GLONASS antenna available.

TW1421支持GPS L1、Glonass G1,仅仅30克重,28dB增益。适合无人机、穿戴式设备。

高增益版本为TW1430,32dB增益;北斗版本为TW1721支持北斗B1、GPS L1、Glonass G1。
