Tallysman TW3040 (and TW3042) Tracking and Timing Antenna
The TW3040 (and TW3042) by Calian is a professional grade, permanent mount GPS L1 antenna, specially designed for professional precision timing applications.
Â
The TW3040 features a custom high performance, wide band patch element, a 40dB 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, and it provides great axial ratio, excellent circular polarized signal reception, great multipath rejection and great out-of- band signal rejection.
Â
The TW3040 is housed in a permanent mount industrial-grade weather-proof enclosure, and comes with a TNC Jack (female) connector.
Â
Features:
- Great axial ratio
- Low noise LNA: 1 dB
- High rejection SAW filter
- High gain: 30 dB typ.
- Low current: 15 mA typ.
- ESD circuit protection: 15 KV
- Wide voltage input range: 3.0 to 10 VDC
- Weather proof housing: IP67
LNA Pre-filter Available
If you need enhanced protection against high level sub-harmonic signals like LTE and near frequency signals such as WiFi, the alternative TW3042 provides these additional benefits with an LNA pre-filter.
To minimize performance impact from signal jamming threats, the pre-filtered version of this antenna is compatible with Tallysman’s Anti-Jamming add-on, which modifies the radiation pattern of the GNSS antenna to eliminate signals arriving from -10° to +15° from horizon, while slightly increasing the gain of the antenna at zenith.
