MA-620L Marine GPS Antenna
  • Descrizione del prodotto
  • Caratteristiche del prodotto
  • Specifiche di prodotto

Small size and ruggedness, demand of vehicle locating and marine navigation GPS antenna that will sustain harsh environment.

  • Low noise figure
  • Fully weather proof.
  • Ultra-high Sensitivity
  • Compact construction
  • Excellent temperature stability
  • FB3A SUS L-Mounting 1"-14 UNS

The antenna system MA-620L is the integration of the high performance GPS patch antenna and a low noise amplifier into state-of-the-art low a very low profile/extremely compact/fully waterproof antenna signal enclosure. When connected to a GPS receiver with +3~5V DC antenna power it provide excellent signal amplification and out-band-rejection for that receiver.

GPS antenna with double threaded bolts and through holes for cable routing with course & fine treaded pitch locking for wing-nut fastener and lock-nut to prevent vibrations and un-authorize removal.
