TW1430 Accutenna® Embedded Single-Band GNSS Antenna

The TW1430 is a higher gain version of the TW1421 designed to meet the specifications of receivers requiring the higher gain, such as the Trimble BD9xx family of receivers.

The TW1430 employs Calian's patented Accutenna® technology covering the GPS-L1, GLONASS-G1, and SBAS (WAAS, EGNOS & MSAS) frequency band (1575 to 1606 MHz). It provides truly circular response over its entire bandwidth thereby producing superior multipath signal rejection. It also offers high out-of-band signal rejection.

The TW1430 features a novel 25 mm wideband patch element with dual-feeds that are summed in a 90° Hybrid and input to a two stage low-noise amplifier (LNA), with a midsection SAW, and a second low noise gain stage. This configuration provides excellent axial ratio crosspolarization rejection across the full frequency band.

The built-in 35 mm circular ground plane should ideally be augmented with a local system ground plane or reflecting surface (DC connection not required).

There are two options: TW1430S which has a lower profile can, mico-coax cable, and a U.FL. connector; or TW1430T which has a taller can, RG174, and a choice of connectors.
