Overview

The TW2100/TW2102 employ Tallysman’s unique Accutenna technology in a magnet mount GPS L1 antenna, specially designed for industrial, agricultural and military precision positioning and timing applications.

The antennas feature a custom high performance, dual-feed, wide band patch element. Its LNA configuration provides a LNA for each feed, a mid section high rejection SAW for the combined signal, followed by a final stage of LNA. It provides ±10MHz bandwidth centred on 1575.42 MHz and covers all GPS L1, and SBAS (WAAS/EGNOS/MSAS) signals. It features great axial ratio over the entire frequency range (<3dB), excellent circular polarized signal reception, great multipath rejection and out-of-band signal
rejection.

The TW2102 has a pre-filter to provide strong protection against near frequency and harmonic signals.

The antennas are housed in a compact, industrialgrade weather-proof, magnet mount enclosure and a wide range of connector.
