TW3010 GPS 28dB Tracking Antenna
The TW3010 by Tallysman Wireless is a professional grade, permanent mount GPS L1 antenna, specially designed for professional tracking and timing applications.
The TW3010 features a custom high performance, wide band patch element, a 30dB gain LNA stage and a high rejection out-of-band SAW filter. It provides ±10MHz bandwidth centred on 1575.42 MHz and covers the GPS L1, Galileo E1 and SBAS (WAAS/EGNOS/MSAS) signals. It provides great axial ratio, excellent circular polarized signal reception, great multipath rejection and great out-of-band signal rejection.
The TW3010 is housed in a permanent mount industrial-grade weather-proof enclosure, and comes with a TNC Jack (female) connector.
