## A Tallysman _Accutenna[®]_ TW3400/TW3402 GPS/GLONASS Antenna 

The TW3400/TW3402 employs Tallysman’s unique _Accutenna_ technology covering the GPS L1, GLONASS L1 and SBAS (WAAS, EGNOS & MSAS) frequency band (1574 to 1606 MHz).  They are especially designed for precision industrial, agricultural and military applications. .  They provide truly circular response over the antennas’ entire bandwidth thereby producing superior multipath signal rejection. 

The TW3400/TW3402 feature a highly circular dualfeed 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 on the TW3402 to protect against saturation by high level sub-harmonic and L-Band signals. 

TW3400 Dimensions (mm) Flat radome is shown, Conical Radome also available 

The TW3400/TW3402 is housed in a permanent mount industrial grade weather-proof enclosure.  Two options for pole mounting are available an L-bracket (P/N#23-0040-0) or a pipe mount (P/N#23-0065-0).
