TW4027/TW4029

The TW4027/TW4029 is a very low power, compact GNSS antenna covering the GPS L1, frequency band. This antenna features an LNA with a nominal current consumption of just 2mA, with constant performance from 2.5V to 15V supply voltage, and includes protection against close proximity L-band transmitting antennas such as Iridium™ and Globalstar™

Features

  • 40% wider bandwidth
  • Amongst the lowest power consumption available
  • Low noise LNA: 1dB
  • Temperature compensating LNAs

Benefits

  • Great out-of-band signal rejection
  • Excellent signal-to-noise ratio
  • Consistent response in all operating
    temperatures

The TW4029 variant provides a “Brick-Wall” pre-filter to protect against saturation by high level sub-harmonics and L-Band signals.

The TW4027/TW4029 are housed in a compact, magnetic mount, IP67 compliant housings. It is RoHS and REACH compliant.
