TW2410/TW2412 双馈GPS/Glonass高精度天线
The TW2410/TW2412 employ Tallysman’s unique Accutenna™ technology which provides truly circular response over its entire bandwidth thereby producing superior multipath signal rejection resulting in higher positional and timing accuracy. The TW2410 covers the GPS L1, GLONASS G1, and SBAS (WAAS, EGNOS & MSAS) frequency bands (1574 to 1606 MHz). The TW2410 is also available in an OEM / embedded version – the TW2405.

- Great out-of-band signal rejection
- Excellent signal-to-noise ratio
- Consistent response in all operating
temperatures
The TW2412 has an additional tight pre- filter to protect against saturation by high level sub-harmonics and L-Band signals.
The TW2410/TW2412 are housed in compact, magnetic mount, IP67 compliant housings. The antenna can be ordered without the magnet. In such cases, the magnet is replaced with a plastic plug to provide a smooth under surface. 有免磁可选、螺丝固定安装。
They are RoHS and REACH compliant.
