NTA 3E-SHT

Short Active three-frequency NAVTEX Receiving Antenna
Description
  • Specially designed for the three NAVTEX frequencies 490 kHz, 518 kHz and 4209.5 kHz.
  • Built-in low-noise amplifier providing excellent impedance matching to the 50 Ω downlead cable.
  • Special band-pass filter based tuning circuitry to optimize the antenna for the NAVTEX frequencies and protect from possible interference from e.g. medium wave broadcast radio signals.
  • RF ground internally AC-coupled to mounting bracket preventing electrolytic corrosion.
  • Sturdy design to withstand the roughest weather and climate conditions.
  • Simple mounting using the 1” revolving nut system.
  • Wide varity of accessory mounting brackets available.
  • Junction kit for easy connection to receiver and DC power supply available (to be ordered separately).
