TW4821 Wideband Dual Feed BeiDou/Galileo/GPS
Antenna
The TW4821 by Tallysman Wireless is a compact
dual feed magnetic mount antenna covering the
BeiDou B1, GPS L1, Galileo E1 and SBAS (WAAS,
EGNOS, QZSS & MSAS) frequency band (1557 to 1593
MHz). The TW4821 features a novel 25mm dual feed
wideband patch element that provides excellent
multipath rejection and a more linear carrier phase
response by virtue of the axial ratio that is greatly
improved across the full frequency bandwidth. It is
especially suitable for high accuracy applications, and
also offers high out of band 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.
The TW4821 is the smallest dual feed, high
performance antenna available. It is housed in a
compact IP67 magnetic mount enclosure. It is
available with a wide range of connector options.
Applications
Cost Sensitive Mission Critical Positioning
Military & Security
Covert surveillance
Fleet Management & Asset Tracking
