TW3400/TW3402 高精GNSS天线

The TW3400/TW3402 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 timing.

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。

The TW3402 has an additional tight pre-filter to protect against saturation by high level sub-harmonics and L-Band signals.

The TW3400/TW3402 are housed in a through-hole mount, weather-proof enclosure for permanent installations. They are available with either a flat or conical radome in either grey or white. The TW3400/TW3402 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. They are IP67, RoHS, and REACH compliant.
