  • Excellent signal to noise ratio
  • Great out of band signal rejection
  • Increased system accuracy
  • Ideal for harsh environments
  • RoHS and REACH compliant

Details

Ideal for high-accuracy applications the TW3712 provides truly circular response over its entire bandwidth thereby producing excellent multi-path and out-of-band signal rejection.

TW3712 antennas features a dual-feed wide-band patch element, with a two stage Low Noise Amplifier (LNA), comprised of one input LNA per feed, a mid section SAW to filter the combined output, and a final output gain stage.

Providing enhanced protection against high level sub-harmonic signals like LTE and near frequency signals such as WiFi, The TW3712 also includes an LNA pre-filter.

The TW3712 provides excellent axial ratio that is constant across the full frequency band along with a superb phase linear response and tight phase centre variation.

The TW3712 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. A 100mm ground plane is recommended for non-roof-top installations.

To minimize performance impact from signal jamming threats, the TW3100 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.
