TW3040/ TW3042 Permanent Mount GPS L1 Antenna The TW3040/TW3042 is a professional grade, permanent mount GPS L1 antenna, specially designed for professional precision timing applications. The TW3040/TW3042 features a custom high performance, wide band patch element, a 40dB gain LNA stage and a high rejection out-of-band SAW filter. The TW3042 is equipped with a sharp SAW pre-filter to provide strong protection from out-of-band signals. It provides ±10MHz bandwidth centred on 1575.42 MHz and covers the GPS L1, Galileo E1 and SBAS (WAAS/EGNOS/MSAS) signals, and it provides great axial ratio, excellent circular polarized signal reception, great multipath rejection and great out-of-band signal rejection. The TW3040/TW3042 is housed in a permanent mount industrial-grade weather-proof enclosure and two options for pole mounting are available an Lbracket (P/N#23-0040-0) or a pipe mount (P/N#230065-0).
