      TW4039 Single Band GNSS Antenna (Pre-filtered)

       

      The TW4039 is very low power, compact GNSS antennas covering the GPS-L1, frequency band. This antenna features an LNA with constant performance from 2.5V to 16V supply voltage, and includes protection against close-proximity 700 MHz LTE and L-Band transmitting antennas.

      The TW4039 provides a minimum gain of 15 dB and 12 dB, respectively and excellent noise figure. The TW4039 patch has 40% wider bandwidth for better axial ratio and has 15 kV ESD circuit protection. The LNA has a +/- 10 MHz bandwidth that covers the full GPS-L1 signal plus the SBAS (WAAS /EGNOS/MSAS) frequency band (1572.5 to 1578 MHz).

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

      It is housed in a compact IP68 magnetic mount enclosure. The antenna can be ordered without the magnet. In such cases, the magnet is replaced with a plastic plug to provide a smooth under surface, with the option of ordering it with or without 1.1 mm thick doublesided VHB tape on the bottom.
