- RoHS and REACH compliant The TW3 100 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 s ection 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 f requency 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 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) A Tallysman Accutenna® TW3100 / TW3102 Permanent Mount GPS L1 Antenna TW3100 Dimensions (mm)
