Tallysman TW2410 and TW4421 dual-feed GPS/GLONASS antennas

Click2Contact

The TW2410 and TW4421 are dual-feed GPS/GLONASS antennas from Tallysman’s GNSS antenna range. The antennas cover the GPS L1, GLONASS G1 and SBAS (WAAS, EGNOS and MSAS) frequency band (1574 to 1606 MHz) and feature a dual-feed wideband patch element. The dual-feed patch provides good circular polarised signal reception, multipath rejection and out-of-band signal rejection.

With a tight phase centre variation (PCV), the antennas are especially suitable for high-accuracy applications and for use in precise point positioning (PPP) systems that require only a single frequency, such as single-frequency RTK solutions, GNSS compasses and machine control. Designed for precision industrial, agricultural and military applications, the dual-feed GPS/GLONASS antennas feature Tallyman’s Accutenna technology that provides good multipath signal rejection and precision.

The TW2410 and the TW4421 are housed in IP67 industrial-grade, weatherproof, magnet-mount enclosures and come with a wide range of connector options and cable lengths. The TW4421 is claimed to be the smallest dual-feed, high-performance antenna available.
