Datasheet:Overview
Tallysman Wireless’ TW1421 GLONASS/GPS Antenna is a dual-feed OEM device, which covers the G1 GLONASS, L1 GPS and SBAS (EGNOS, MSAS, WAAS) frequency band.
A low axial ratio is provided by the dual feed architecture, which makes the unit suitable for high precision applications. It also has a linear carrier phase response as well as excellent multipath rejection and offers excellent out-of-band signal rejection.
The TW1421 has a wideband dual-feed patch element input to a Low Noise Amplifier with two stages, mid-section SAW and another low noise gain stage. This enables great axial ratio as well as cross polarization rejection over the complete frequency band.
Applications include high accuracy GLONASS and GPS, precision agriculture, military and security, mining and construction, avionics, law enforcement and public safety, fleet management and asset tracking. The company helps OEMs integrate the product into end-user solutions.
