TW2410-00

## A Tallysman _Accutenna™_ TW2410/TW2412 Magnetic Mount GPS/GLONASS Antenna 

The TW2410/TW2412 employs Tallysman’s unique _Accutenna™_ technology covering the GPS L1, GLONASS L1 and SBAS (WAAS, EGNOS & MSAS) frequency bands (1574 to 1606 MHz).  It is especially designed for precision industrial, agricultural and military OEM applications.  It provides truly circular response over its entire bandwidth thereby producing superior multipath signal rejection. 

The TW2410/TW2412 features a dual-feed wideband patch element, with a two stage Low Noise Amplifier, comprised of one input LNA per feed, a mid section SAW to filter the combined output, and a final output gain stage.  This configuration provides excellent axial ratio that is constant across the full frequency band. An optional tight pre-filter is available with part number TW2412 to protect against saturation by high level sub-harmonics and L-Band signals. 

The TW2410/ TW2412 is housed in a compact, industrial-grade weather-proof, magnet mount enclosure, and is available with a variety of connectors and cable lengths.
