Tallysman TW3100/TW3102

TW3100/TW3102 Permanent Mount GPS L1 Antenna

The TW3100/TW3102 employ Tallysman's unique Accutenna technology covering the GPS L1 and SBAS (WAAS, EGNOS & MSAS) frequency bands (1574 to 1606 MHz). It provides truly circular response over its entire bandwidth thereby producing superior multipath signal rejection.

Overview

The TW3100 and TW3102 employs Tallysman’s unique Accutenna technology in a permanent mount GPS L1 antenna, specially designed for professional precision tracking and timing applications.

The TW3100 features 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, Galileo E1 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 TW3102 has a prefilter to provide additional protection from high power near frequency or harmonic signals.

The TW3100 is housed in a permanent mount industrialgrade 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).
