Details
Ideal for high-density, telecommunications tower timing applications, where high levels of near-out-of-band interfering signals are common, the TW3142 provides excellent circular polarized signal reception, great multi-path and out-of-band signal rejection. Additionally, with a high gain Low Noise Amplifier (LNA) of 50 dB, the antenna is able to support long cable runs often necessary for tower installation.
The TW3142 features a customizable dual-feed, wide-band patch element, with a dual-stage Low Noise Amplifier (LNA), and provides an excellent axial ratio that is constant across the full frequency, superb phase linear response and tight phase centre variation.
To minimize performance impact from signal jamming threats, the TW3142 is compatible with Calian’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.
The TW3142 is housed in a permanent mount industrial grade weather-proof enclosure, available in conical or flat radome styles and in grey or white colours. Two options for pole mounting are available an L-Bracket or a Pipe Mount.
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 TW3152 provides these additional benefits with an LNA pre-filter. Click here to learn more about the TW3152.
