  • Wide voltage input range: +2.5 to 16 VDC

Benefits

  • Circular polarization throughout the full bandwidth
  • Superior multipath signal rejection
  • Excellent signal to noise ratio
  • Great out of band signal rejection
  • Increased system accuracy
  • Ideal for harsh environments
  • IP67, RoHS and REACH compliant

Details

Ideal for professional precision timing applications, TW3740 provides excellent circular polarized signal reception, great multi-path and out-of-band signal rejection.

The TW3740 features a customizable dual-feed, wide-band patch element, and a 40 dB gain Low Noise Amplifier (LNA) with a high rejection out-of-band SAW filter, providing an excellent axial ratio that is constant across the full frequency, superb phase linear response and tight phase centre variation.

The TW3740 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 TW3742 provides these additional benefits with an LNA pre-filter. Click here to learn more about the TW3742.
