TW4421-00概述

TALLYSMAN WIRELESS  TW4421-00  天线, GPS / GLONASS, 1.574-1.606GHZ

The is a wideband dual-feed GPS/GLONASS Antenna suitable for high accuracy applications and also offers high out of band signal rejection. The TW4421 employs Tallysman"s unique Accutenna™ technology covering the GPS L1, GLONASS G1 and SBAS WAAS, EGNOS and MSAS frequency band 1574 to 1606MHz. The TW4421 features a novel 25mm dual-feed wideband patch element that provides a more linear carrier phase response by virtue of the axial ratio that is greatly improved across the full frequency bandwidth. It provides truly circular response over its entire bandwidth thereby producing superior multipath signal rejection. The two feeds from the patch element are summed in a 90° hybrid then input to a first stage low noise amplifier LNA, followed by a mid-section SAW and a second low noise gain stage. It is housed in a compact IP67 magnetic or adhesive mount enclosure. It is ideal for harsh environments.
